Our Review

Wellness is a company whose roots in pet-food manufacturing date back to the 1920s. They own their own manufacturing facilities, however wet food is co-manufactured with Simmons Pet Food. The Paté formulas are pretty well-liked by most cats and can be fed exclusively or over kibble. We like a lot of the natural ingredients that contain essential nutrients and thoughtful ingredients such as cranberry and kelp. Wellness is an affordable choice for your kitty.

Our Review

Farmina canned cat foods are made in Europe using ingredients sourced from Europe and New Zealand.  This product is advertised as being “steamed directly in the can” to preserve nutrient content.  This is an above-average canned food made without thickeners, although it does contain sweet potato as a vegetable filler.  This food contains a high level of protein content from quality animal sources, low fat, and carbohydrates, and many of the nutrients are chelated or proteinate to improve absorption.  We didn’t like the inclusion of the aforementioned sweet potato and the presence of DL-methionine, a synthetic (rather than natural) form of an essential amino acid.  The cans are BPA-free.

Complete nutrition in each recipe means this diet can be fed on its own without supplementation.

Our Review

This high-quality wet cat food from Hounds & Gatos impressed us with the 98% chicken/liver ingredients.  There are no fillers and these wet foods appeal to a lot of kitties. Their meats are sourced from the US and EU. While Hounds & Gatos has a lot of different flavors of wet foods, we chose this one for a single-source protein. Some cats do better with one source of protein than multiple animal sources. Fish oil is contained in this but not a main ingredient, so it should not aggravate allergies. We aren’t as fond of the use of agar-agar, which can be a bowel irritant in felines Cans are BPA free, and the Hound & Gatos facilities follow FDA/USDA regulations and food is tested regularly. We’d like to more transparency on where other ingredients are sourced.

Our Review

Dr. Elsey’s foods were developed by a veterinarian and his wife. Their Cleanprotein Duck Formula Canned cat food is a moderately strong option for wet cat food.  This food prioritizes animal protein sources that rank among the highest in terms of biological value.  It has a lower glycemic formula and little to no oxalate to promote urinary health.  We like the high protein and moisture content, inclusion of quality sources for omega-3 fatty acids, low carbohydrate content, and the absence of grains and other fillers.  This food also includes natural flavor (although naturally sourced, “natural” flavors typically come from a variety of natural products that may or may not be healthy for cats).

Additionally, we would like to see more transparency from Dr. Elsey’s on where their foods are made and which ingredients are sourced from China. They indicate that 90% of the ingredients are sourced from the US. Many manufacturers source taurine from China as it’s difficult to find it elsewhere.

FirstMate canned foods are advertised as having limited, simple ingredient recipes.  The Turkey Formula Limited Ingredient Grain-Free canned food derives 96% of its protein from turkey and 4% protein from vegetables.  We like the relatively high protein content, low fat content, and minerals that are chelated or proteinated for better absorption.  We aren’t too fond of the inclusion of vegetable protein and starch from potatoes.  This food is manufactured in Canada, with no Chinese-sourced ingredients.  The can liners are BPA-free.

Tiki Cat’s wet cat foods don’t have potato or grain and the whole meat ingredients in them are a high-quality protein source. What’s in the can actually looks recognizable as meat. Even better, we love that the cans come in smaller sizes. If you are only feeding one kitty, you know how it is, there’s always a can of cat food in the refrigerator, and a smaller can means the food is fresher, with less waste. Tiki Cat is a great value too and affordable. Initially, we were turned off by the fact that these foods are packed in Thailand but after some research, we’re ok feeding this to our own kitties. These are packed in human food plants with regionally-sourced ingredients, and some of these facilities make US canneries look downright medieval in comparison. Thailand’s oversight of food production, both human and pet is far more extensive than in the US.

Tiki Cat also has wet treats, broths, mousses, and other treat options for your cat. Liquid treats and broths are a good way to get moisture into a cat who is addicted to dry food, or won’t eat a limited diet. Feed in moderation as these have emulsifiers in them (but no carrageenan).

We’re big fans of Feline Natural. These wet foods include high-quality protein sources, no by-products or fillers, and have a natural anti-inflammatory bonus of New Zealand green-lipped mussel. This formula mimics a carnivore’s prey diet by including nutrient-dense organs like kidney, heart, and blood that she’d eat in the wild. You definitely get what you pay for here, but you pay a lot, and a lot of pet parents may find it more economical to use this as a supplement. We love the option of a smaller can for less waste and not having to have that pesky can of smelly cat food in the refrigerator.

Our Review

Ziwi Peak is one of the best wet cat foods we’ve come across, paws down. For its slightly lower price point we chose to review the chicken recipe, but this has a 2% lower protein content than the pricier varieties such as the lamb and rabbit. All of the Ziwi Peak foods contain green mussels, which have nutrients to keep your kitty’s joints and cartilage healthy. These foods are loaded with single-sourced meats, organs, and bones- simulating wild prey foods. These are sourced from animals that are free-range and grass-fed. No rendered meals or nasty fillers, emulsifiers, etc.

It is important to note that if you are considering transferring your cat to a premium food like this, they may not like it right away since they might be accustomed to the attractants and flavors added to cheaper foods. Kind of like trying to get a teenager to eat less junk food and more broccoli, it will take time to get your feline to eat better.  Our personal cats prefer chicken and rabbit wet foods over those containing fish or lamb, but results may vary as felines are picky!

Scared off by the price tag? We recommend you look at some of Ziwi’s freeze-dried varieties as well, you can add liquid to some of these to reconstitute and it may be a better value.

Nulo is a relatively new pet food brand that as of this writing hasn’t yet been bought up by one of the big pet food manufacturers. You can find the Freestyle line in most big box stores. We really like this particular blend, as it’s popular with both older and young cats, and is a great choice for kittens with a generous fat and protein content for growing muscles, organs and joints.

According to Nulo, its meat, poultry, and fish are sourced in North America except for its duck, which comes from France, its lamb, which is sourced from New Zealand and Australia, and wild-caught fish which is caught globally based on migration routes. Nulo does not source anything from China.

Nulo’s wet pate foods are manufactured in the U.S. but we could not determine what facility. Their wet cat food pouches and purees are made in Thailand, like Tiki Cat. The brand has never had a recall.

Our Review

Some cats really like morsels in gravy as an alternative to a pate in a can or shredded meat in wet food, and Castor & Pollux’s pouches are easy to feed. They are not resealable. The liver in this mix can make it more palatable to some cats who are picky eaters. Other flavors in the Pristine line that our cats like are the plain chicken, salmon, chicken and turkey, tuna recipe, and plain turkey.

While this blend has four protein sources ahead of it on the ingredient list, this still has dried peas in it. Minerals listed are chelated or proteinate which will make them more readily absorbed by your cat. Castor & Pollux has indicated they are attempting to move completely away from sourcing their vitamins/supplements from Chinese sources but at this time there is no definitive statement from the company about where these ingredients come from.

Castor and Pollux was bought by Merrick, and then Merrick was bought by Nestle Purina. However,  their canned and dry food lines are still manufactured by Merrick Pet Care’s plant in Hereford, TX. We do not recommend purchasing any food from Merrick that has any meat meals or by-products listed in the ingredients as they are a card-carrying member of Animal Protein Producers Industry (APPI), which is an animal rendering organization. Merrick has also had quality control issues with their canned cat and dog foods, so we recommend sticking with the pouches.

Our Guide to Cat Food: Wet Food Emphasis

Your kitty’s thirst drive, or instinct to drink water is usually not adequate to have her drink enough water from her bowl or fountain to get enough water on her own. That’s where wet cat food can be an important part of her diet.

Whether you’re looking to begin feeding your cat a wet food diet, adding more moisture to her diet, or concerned about her level of nutrition, the choices can be overwhelming. Marketers entice you to buy wet cat food by comparing it to a fine restaurant offering or a well-balanced human meal. Remember that your feline companion is a carnivore and not a gourmet food critic!

The pet food industry makes it difficult on purpose to see past the commercials showing dreamy, spoiled and fluffy cats indulging on an “entrée” or whatever human food terminology they use to describe canned cat food. Billion-dollar marketing campaigns designed to appeal to your emotions can make it hard to judge what’s actually best for your kitty.

In 2018, nearly 90% of all pet food was made by the same 6 companies churning out food under 106 different brands.

Wet cat food has the reputation of being smelly and not nearly as easy as a dry kibble diet to feed your cat. After all, you can’t load it into an automatic cat feeder or leave it out all day for your kitty to nibble at her leisure. Canned pet food has been around since the 1920s, and while it’s definitely come a long way in terms of quality and content, some things haven’t changed. One thing that has remained consistent is that cheap wet cat (and dog) food often contains some of the sketchiest ingredients you can imagine.

With news of recalls, class-action lawsuits, and studies that all seem to conflict each other- it can be challenging to choose the best quality wet food for your cat.

Our team has done the hard work and hundreds of hours of research for you. Based on scientific studies, data, testing, and interviews with our own trusted vets, our guide will help you make informed choices on cat food. Learn what goes into cat food, how to read labels and the pet food industry’s role in defining standards. In this review and guide, we’re covering wet food.

The Complete Spots Guide to Cat Food: Wet Food Emphasis

The popularity of wet cat food took a bit of a nosedive when extruded dry kibble-style cat food hit the market. While it made feeding a cat easier and cheaper, dry cat food has also brought with it a growing epidemic of health problems. A lot of dry cat food (even the high-end and prescription stuff!) is made with fillers, binders, and grains because they’re cheap for manufacturers to use. Due to its low moisture content, dry cat food cannot deliver the right amount of moisture to cats, who in the wild get most of their water content from the prey they eat.

This is why wet food is once again becoming a popular choice for pet parents who want to feed a more biologically correct diet containing sufficient moisture to their kitties. There are many opinions out there on the matter, but the facts stand: cats are carnivores, and since the pet food industry began to grow, domesticated kitties became the only ones not eating a steady diet of raw prey-based animal protein. It is biologically necessary for them to eat meat, and unlike dogs, their bodies have not evolved to obtain critical nutrients from other sources.

Forms of Wet Cat Food:

Commercially wet food comes in many consistencies:

  • Pate, minced, flakes, morsels, gravies, chunks, and shredded
  • Gravies and formulas with the food suspended in gravy often have thickeners or emulsifiers in them

And as with all dog foods, there are varying levels of quality with wet food as well.

  • Human-grade canned food- food
    • Meets USFDA standards from source to finished product. Even though a protein source came from a USDA plant, unless specifically manufactured, packed and held in accordance with federal regulations, it is not considered human-graded.
  • Premium Canned Wet Food
    • Typically has whole meat/high quality protein as first, second ingredient
    • Fewer fillers, preservatives, and sketchy additives
  • Grocery or Store Brand Wet Food
    • May have meat by-products as one of main sources of protein
    • May include colorings, flavorings, and emulsifiers
  • Prescription Diet Wet Food
    • Only sold with veterinarian prescription
    • Frequently contain low-quality proteins, fillers, and cheap ingredients

The Real “Science” Diet:

 Cats are obligate carnivores, meaning they have to source their required nutrients from other animals. Many other animals are able to synthesize certain nutrients but cats cannot. In the wild, cats get most of their moisture from their prey. They can ingest plant matter (found in digestive tracts of prey animals) but for the most part, their bodies cannot properly metabolize nutrients from it. Most commercial diets for cats do not provide biologically appropriate nutrition or sufficient moisture. Because cats have a low thirst drive, domestic kitties often live most of their lives in a state of dehydration.

A biologically appropriate diet isn’t a fad. It’s how every other cat in the world eats.

Excessive carbohydrates in a cat’s diet can strain her digestive system over time and result in degenerative disease. A diet based solely on plant-based protein can leave her without essential amino acids. Ever wonder why some cats get smaller as they age? Our felines require specific types of protein to survive, and if they do not get enough of it, their bodies will break down its own muscles and organs to obtain it.

  • Your cat’s jaws open and close up and down with a lateral mandibular swing, meaning food is not chewed and ground down as a herbivore or omnivore creature like a cow might.
  • Her eating style means tearing her food and gulping it down with little to no chewing.
  • She has a short digestive tract for fast digestion and expelling with little to no fermentation.
  • Your cat has a low thirst drive as in the wild she’d get most of her water from prey, which is usually between 65%-75% water.

Remember, your kitty’s diet in the wild would include a high amount of moisture in the raw meat and body parts of her prey. And a domestic kitty is no different- her diet should include as much moisture as possible. And always provide multiple sources of water for her to drink from, including a pet fountain, so she always has a source of fresh, clean water.

Most canned cat food has 75%-78% moisture compared to dry foods, which average between 10% and 15%.

The ideal diet for your cat contains:

  • Low carbohydrates
  • Moderate fats content
  • High levels of moisture
  • High level of quality protein
  • Minimal preservatives and additives

Dogs have evolved to be able to eat just about anything– but domesticated cats have not, and they will not thrive on the average commercial diet. Remember, your kitty is a carnivore, and in the wild, what carnivores eat may not be palatable to humans. It’s important to try and offer a biologically appropriate diet to a cat to the extent possible.

A cat will eat what they must or what they are accustomed to, even if it’s making them sick or slowly killing them. Most cats can’t hunt their own food and will eat what’s put in front of them. After all, what choice do they have?


Food as Preventative Medicine:

When you think of what to buy your cat to eat, the question is usually “will she like it? Will she throw this up at 3 am?” Sometimes it’s the slick advertising or recommendation from a veterinarian or a friend that influences our decision on what to buy. We now know that what you feed your kitty is one of the most important factors in her risk factor for disease.

Most veterinarians are not focused on nutrition for your cat until she becomes sick. They are not usually trained to do so. When your cat gets sick, many vets recommend a “prescription” food no matter what her ailment is. Some “prescription” foods are the worst thing you could do for an animal who is very likely already sick from eating processed food her body wasn’t designed to digest in the first place.

 The bulk of research on pet food is funded by the pet food industry.

The pet food industry designs or sponsors a significant portion of curriculum materials and programs for the nutrition training veterinarians receive in school. When these vets recommend switching a pet to a fresh food diet, it is almost always a temporary approach initiated by a health problem rather than a recommendation for ongoing health and prevention of future disease.

When your cat’s body has to work twice as hard to try and gain nutrients from an inappropriate diet, it can cause serious problems for her long-term health.


Guide to Ingredients & Labels:

 Nutritional adequacy, digestibility, natural, premium, organic… what does it all mean?

As we said before, buying pet food is meant to be confusing and billion-dollar marketing campaigns play on our emotions and love for our animals. Understand that your beloved talk show host does not spend her days in a giant kitchen cutting up prime cuts of meat just for your kitty and “gourmet” and “premium” mean nothing in the regulatory world.

Terminology:

First of all, we’re going to discuss some of the common terms you see on packaging and in descriptions.

  • “Complete, Balanced” – The FDA and AAFCO require foods with this verbiage to provide a complete level of nutrition, established by the AAFCO. If it does not state that “(Product Name) is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles,” it’s not going to be good as the sole source of nutrition you feed your animal .
  • “All Life Stages, For Maintenance, For Growth, For Senior Cats” – The nutritional adequacy standards for various stages of life are different. Obviously, kittens or reproducing mama kitties need different levels of nutrition than an adult cat of normal activity. There is no nutritional standard or guideline for a senior cat, other than it meets the needs of an adult maintenance diet.
  • “Premium, ultra premium, super premium” – These mean nothing and there is no standard they are required to meet.
  • “ Natural” – This is one area that does have some (laughable) oversight. According to AAFCO:

(1)  In the AAFCO-defined feed term “natural,” the use of the term “natural” is only acceptable in reference to the product as a whole when all of the ingredients and components of ingredients meet the definition.

(2) In the definition, the use of the term “natural” is false and misleading if any chemically synthesized ingredients are present in the product; however, AAFCO recommends that exceptions be made in the cases when chemically synthesized vitamins, minerals, or other trace nutrients are present as ingredients in the product, provided that the product is not a dietary supplement and that a disclaimer is used to inform the consumer that the vitamins, minerals or other trace nutrients are not natural.

 However—“Exceptions be made when the term “natural” is used only in reference to a specific ingredient (e.g. “natural cheese flavor”) even though the product as a whole may not meet the definition of the AAFCO-defined feed term “natural” and that the reference does not imply that the product as a whole is “natural.”

  • “AAFCO guaranteed” AAFCO does not certify or endorse specific foods, it defines what an ingredient must actually include to be considered accurately labelled.

AAFCO definitions of products are either deliberately vague enough to allow manufacturers a lot of wiggle room. Under AAFCO’s regulations, commercial pet food is sold that continues to make hundreds of cats and dogs sick.

Ingredients:

We’ve picked some of the most common ingredients encountered in cat food, both good and bad, expensive and cheap.

 

Carbohydrates

Cats in the wild typically only consume carbohydrates contained in the digestive systems of their prey.

Even expensive cat foods often have high levels of carbohydrates in their foods because it is cheap to use. These products have a high glycemic index, causing them to raise your pet’s blood sugar levels, change hormone balances, cause obesity/digestive problems in a cat. Worse, they can aggravate allergies. It is best to try and keep the percentage of carbohydrates your cat eats in her food at 10% or lower.

Do you notice how manufacturers never list the carbohydrate content on packages? They don’t have to, and most won’t. That’s because most cat food is packed with it. And it’s the worst thing you can feed a feline whose body is not designed to metabolize it. A consumer cannot tell the carbohydrate content of cat food based on their label alone.

If your cat’s food contains high-carb ingredients such as grains, potatoes, peas, etc. it has carbohydrates.

 

Grains

You eat grains, so it’s ok for your pet to, right? Chances are, your pet is not eating the same grade of grain that went into the bread you just used to make a sandwich.

Grain rejected for human consumption heads straight to the pet food factory- After all, it is not required to meet the same standard. Grains in pet food may include unacceptable levels of deadly substances:

  • Herbicides, pesticides, and fungicides sprayed onto the crops (often occurring in grains sourced from the outside the US)
  • Mycotoxins- substances produced by mold growing in grain that may not be completely destroyed by cooking/processing

Pseudo Grains

Growing in popularity in pet foods are these non-traditional grains such as amaranth and quinoa. They both contain high levels of naturally occurring protein, minerals, and fiber but may still break down into excess sugar incorrectly.

 

Legumes

These commonly used ingredients include lentils, peas, pea flour, pea protein, chickpeas, etc.

 

Emulsifiers

Ingredients like guar gum, carrageenan, xanthan gum are added to commercial cat food, especially in pouch foods with “gravy” and sauces” as these likely have these emulsifiers in them to make them thick.

  • Carrageenan is derived from seawood processed with alkali for use as a “natural” ingredient to thicken food. When processed with acid “degraded,” it is extremely inflammatory to the point where scientists use it to induce inflammation in lab animals. Carrageenan may change to a degraded and highly inflammatory form once it is exposed to the acids in the stomach.

 

Preservatives

No legal requirement currently exists in the US to label these. Some are not harmful to your cat in moderation but they are not clearly labeled. Some of these may not be on the ingredient list for your kitty’s food. However, it does not mean that the raw material used to make that food did not have it added before it went to the manufacturer. Common offending preservatives to avoid:

  • Sulfite/Potassium sulfite- leads to Vitamin B deficiencies
  • BHA, BHT- Butylated hydroxyanisole and butylated hydroxytoluene are antioxidants that prevent rancidity in the fatty contents of cat food
  • Ethoxyquin- antioxidant preservative originally developed by Monsanto as a rubber stabilizer and pesticide- later refined for use in pet foods
  • Ethoxyquin is added to fish meal before it reaches the manufacturer and may still be present in the food even if it’s not listed on the ingredient list
  • Nitrate, Sodium Nitrate
  • Preservatives that are better suited for your kitty include Vitamin C and E, and these may be referred to as tocopherols

 

Proteins: Plant-Based

These are not ideal for cats due to inferior amino acid profiles. Your cat is not a vegetarian or vegan and without animal proteins, she will be malnourished. I once overheard my favorite vet telling somebody that “If you want an herbivore for a pet, you should get a rabbit.”  

  • Soy ingredients- Soybeans and derivative products can affect a cat’s thyroid and contain phytoestrogens. There is no reason for a soy product to be in a food other than that it’s cheap and helps a company’s bottom line.
  • Soybean Protein Concentrate- a product made from soybeans that removes carbohydrate content from the soybean leaving behind protein. This process can reduce the quality of the included protein.
  • Wheat Gluten- made from a wheat flour dough that is processed to remove starches, leaving behind only gluten, a substance used as a filler and to boost protein content.
  • Legumes: These commonly used ingredients include lentils, peas, pea flour, pea protein, chickpeas, etc. that all contain a relatively high level of carbohydrates. These may boost the protein content of a food and are certainly better than grains like corn or wheat, but they still contain carbohydrates.

Proteins: Animal-Based 

The requirement for protein in a cat’s diet is critical. Animal-based proteins offer your cat a complete amino acid profile, something plant-based proteins lack. There are 23 specific amino acids a cat requires to be healthy, and 10 of them she cannot produce herself, meaning she must get them through her food. Even one missing from her diet can make her ill.

  • Arginine- helps your cat’s body flush ammonia from her body through urine, and without it, the buildup of ammonia in her bloodstream could become toxic.
  • Taurine- deficiency can result in retinal degeneration/blindness, hearing loss, cardiomyopathy, heart failure, weakened immune system, and congenital defects passed on to any kittens she may have. Taurine is only found in animal proteins.

If these are missing or deficient in her diet, your cat will rapidly become malnourished. Her body will begin to break down and cannibalize itself.

The higher quality of animal protein in the food, the more nutrients will be in it and the easier it will be for your kitty to digest and absorb. Not all protein is the same. There are foods that contain high-quality meat as the primary source of protein and there are foods with “mystery” meat that you don’t even want to know about.

Cheap protein that is derived from rendered meat by-products has very little nutritional value and can put stress on your cat’s digestive system. Over years this can lead to chronic conditions caused by your cat’s body struggling to glean nutrients from terrible food.

Characteristics of high-quality proteins:

  • Fresh muscle, organ meat (heart, lungs, liver, connective tissues)
  • Retain higher level of moisture (or in freeze-dried, will absorb it back upon reconstitution)
  • Contain high levels of nutrients
  • Generate the least metabolic stress

Characteristics of low-quality proteins:

  • Rendered mystery meat “meat by-products”
  • (i.e. feathers, bits from the slaughterhouse floor)
  • Require artificial flavors/fats to be sprayed on it for a pet to want to eat it
  • High temperature for rendering process destroys much of the nutritional value

Additives, preservatives, flavorings, and fillers must then be added to meet basic nutrition standards

The Difference Between Meat, Named By-Products, “Meat” By-products, and Meat Meals:

Note that the AAFCO’s definitions of the following ingredients indicate that they do not include problematic and nutritionally deficient parts of animal carcasses “except in such amounts as might occur unavoidably in good processing practices.” This can include hooves, beaks, feathers, hair, hide, contents of digestive systems including intestines, entrails, blood, hide, etc.

“Good processing practices” are not defined, and if you have observed how rendering plants operate, there is often little done to avoid these problematic bits making it into the mix.

Meat

The clean flesh derived from slaughtered mammals and is limited to that part of the striate muscle which is skeletal or that part which is found in the tongue, in the diaphragm, in the heart or in the esophagus; with or without the accompanying and overlying fat and portions of the skin, sinew, nerve, and blood vessels which normally accompany the flesh. It shall be suitable for animal food.

  • Primarily the muscle tissue of the animal, but may include the fat, gristle and other tissues normally accompanying the muscle
  • May include the less appealing cuts of meat, including the heart muscle and the muscle that separates the heart and lungs from the rest of the internal organs, but it is still muscle tissue.
  • Does not include bone. Meat for pet food often is “mechanically separated,” a process where the muscle is stripped from the bone by machines, resulting in a finely ground product with a paste-like consistency

Named By-Products

These are by-products that specifically name the species of animal that was used to make the by-product or meal.

  • Listed on label as chicken chicken by-product meal, turkey by-product meal, poultry by-product meal, and beef by-product meal
  • Usually includes remnants of carcasses that would otherwise be rejected, such as beaks, wattles, combs, intestines (including feces), undeveloped eggs, feet, necks, etc.
  • AAFCO allows these ingredients to include issues from animals that were never USDA inspected or slaughtered, including animals that have died during transport, in the field and even euthanized animals.
  • For example, AAFCOs definition of poultry by-product “consists of the ground, rendered, clean parts of the carcass of poultry, such as necks, feet, undeveloped eggs, viscera, and whole carcasses, exclusive of added feathers, except in such amounts as might occur unavoidably in good processing practices.

Meat By-Products

Non-rendered, clean parts, other than meat, derived from slaughtered mammals. It includes, but is not limited to, lungs, spleen, kidneys, brain, livers, blood, bone, partially de-fatted low-temperature fatty tissue, and stomachs and intestines freed of their contents. It does not include hair, horns, teeth, and hoofs except in such amounts as might occur unavoidably in good processing practices.

  • This may consist of whole carcasses, but often includes byproducts in excess of what would normally be found in meat meal and meat and bone meal.

Meat Meal

The rendered product from mammal tissues, exclusive of any added blood, hair, hoof, horn, hide trimmings, manure, stomach and rumen contents except in such amounts as may occur unavoidably in good processing practices. It shall not contain extraneous materials not provided for by this definition.

  • Unlike “meat” and “meat by-products,” this ingredient may be from mammals other than cattle, pigs, sheep or goats without further description.

Named Meals

Chicken/Beef/Turkey/By-product meal is something much different- it’s dry, ground up by-product.

  • As an example, poultry meal is the dry rendered product from a combination of clean flesh and skin with or without accompanying bone, derived from the parts or whole carcasses of poultry or a combination thereof, exclusive of feathers, heads, feet and entrails.

Fish

High in protein, fish is a common ingredient in cat food, especially since cats love the taste and smell of it. Products from fish found in cat food include:

  • Fish meal- includes residue from fish-processing plants, including fish cuttings, whole fish, heads, tails, guts, etc. Fish meal may have a higher level of protein but a diet relying heavily on it may put your cat at risk for elevated levels of selenium and mercury in her body.
  • Fish Oil- oil from rendering whole fish or cannery waste (!)

Rendered Meat Products

Rendering plants in the US are where biological waste goes when it doesn’t go to a landfill. Dead, diseased, dying and disabled animals of every sort (roadkill, zoo animals, euthanized and dead pets and shelter animals), waste from restaurants and grocery stores, and the waste from slaughterhouses are all sent to rendering plants. Recalled meat? It also goes to the rendering plant.

Animals that were euthanized contain pentobarbital. This used for anesthesia, and in euthanasia, is what stops their hearts and brains. Euthanized animals from farms and animal shelters end up at rendering plants. While manufacturers claim their pet food does not contain cats or dogs, it is not possible to tell from a DNA test of materials where the animal protein came from after the animal tissues have been heated and processed. As recently as 2018, a recall for pet foods containing pentobarbitol was issued by the FDA. Coincidence? In low doses, it may not kill/harm your cat outright, but she could build up considerable resistance to it.

Meat, carcasses, and other animal tissue from slaughterhouses is often treated with disinfectant to slow down the process of decomposition of animal tissues so they aren’t completely rotten by the time they reach the pet food factory. Carcasses that are rejected for human use or “condemned” are treated with a “denaturing” product that has to be in contact with all body parts, either by slashing and application and/or injection. Various substances are used for denaturing, to include carbolic acid, fuel oils, various coloring, charcoal, phenolic disinfectants, tannic acid, or proprietary substances.

Everything is tossed into giant vats where it’s cooked. Protein is separated from bone, run through cookers to evaporate moisture, and separate the fat. The remaining slurry is spun out forcing the fat to rise to the top. This greasy mix is the source of “animal fat” in many common pet foods. Products from rendering plants that don’t go into pet food are shipped to Asia as a product called “tankage” that is fed to seafood.

Vitamins, Minerals and other Supplements

 Because the base ingredients in most dry foods are so heavily processed and don’t contain a consistent amount of nutrients, it’s usually necessary to go in and add ingredients to make cat food meet certain nutritional requirements. To compensate for nutrients being destroyed in the manufacturing process or decreased potency while food is in storage, it’s a common practice to add higher amounts than your cat needs, which may result in some serious quality control issues and negative consequences.

Not all of the ingredients manufacturers add to meet nutritional requirements can even be absorbed by your cat, they are just a manufacturer ticking a box.

Vitamins

Supplements typically added to cat food include:

  • Vitamin A- retinyl palmitate, an animal source can be digested by your cat, and not the plant-based alternative (beta carotene)
  • B-vitamins: riboflavin, thiamin mononitrate, choline chloride, calcium panthenate, folic acid
  • C-vitamins: ascorbic acid
  • D-vitamins: cholecalciferol, methionine
  • K-vitamins: menadione dimethylprimidinol bisulfite
    • Menadione is a synthetic version of vitamin K meant for poultry food that is cheap to produce, can cause health problems in cats and dogs, and may not metabolize properly

Minerals

Supplements added to pet food include:

  • Iron proteinate, ferrous carbonate, and ferrous sulfate
  • Some cat foods include ferrous sulfate as a preservative
  • Copper oxide, copper sulfate, and copper proteinate
    • Help the body convert iron into hemoglobin
    • Too much copper can cause liver disease
    • Copper sulfate is extremely corrosive and a fungicide, root killer and antimicrobial. It does not biodegrade and is not water soluble.

Taurine

An amino acid that both humans and dogs can synthesize within their bodies from other amino acids. Cats cannot do this and must get taurine from their diet to keep their eyes, digestive system, and immune system healthy. A biologically appropriate diet for a cat would include real meats that include good levels of Taurine.

Many foods do not offer this due to the manufacturing process. Unfortunately, most cat food manufacturers source taurine from China.

Fats

Just as it has with humans, fat gets a bad rap. Moderate fat content in a cat’s food will not make her overweight, but carbohydrates will.  Fats in your cat’s diet can provide essential fatty acids that her body cannot synthesize itself. These play a crucial role in helping her body absorb fat-soluble vitamins and nutrients, cell structure and healthy function.

  • Omega-3 fatty acid deficiency can result in vision and nervous system problems
  • Omega-6 fatty acid deficiency can affect your cat’s metabolism, kidney function, and muscular systems

Other Ingredients:

Flavoring– Palatability enhancers and additives designed to make food more attractive are usually derived from animal tissues, such as hydrolyzed livers. These are often sprayed onto dry food. Synthetic substances like smoke and bacon flavors are more commonly found in treats.

Coloring

Many compounds for coloring are approved for use in cat foods. Coloring is to make the food look more palatable to the human dishing it up than the kitty. Iron oxide is a synthetic coloring used in pet foods to lend a reddish appearance reminiscent of fresh meat. Titanium dioxide is a color additive that brightens colors of food.

Fiber

Fiber is good for your cat’s digestive health and in appropriate quantities can help a kitty lose excess weight. Too much in a cat’s diet can dilute the effects of their food, so it should not amount to more than 10% .


The Pet Food Industry’s Controlling Influence on Veterinary Nutritional Science & Prescription Diets

Unfortunately, nutrition is not discussed at length by most vets with pet parents until the animal is ill, and by then, damage may already have been done. Think about it. When you’re in the vet’s office, it’s usually for something you’re concerned about or getting your cat caught up on her shots. Your vet might ask “And what is Fluffy eating?” and jot something down as they complete an exam. And that’s it.

The truth is that pet nutrition is a controversial and convoluted topic that won’t fit into most appointment time slots at the vet’s office. I personally found out the hard way that a nutritionist who charged a significant fee to see a beloved furbaby of mine had undergone training that was almost completely sponsored or designed by (you guessed it) a “scientific” pet food company. I walked away with their fliers and 10% off prescription diet coupons feeling like I still didn’t know what my cat needed. It is a sad truth that some veterinarians may not give you an unbiased opinion on it if their business plan includes the commission from selling “prescription” cat food. It works very much like the big pharma reps you see passing out swag, mugs, and bringing in catered lunches to doctor’s offices for humans. A company worth billions of dollars can easily afford to give away free animal food to shelters and veterinarian students, sponsor studies, universities, and anywhere else they can influence veterinarians and consumers to buy their products without hesitation. Brand recognition is everything.

“Scientific” food that is “prescribed” by a veterinarian has long been perceived by many Americans as a complete source of nutrition and the best possible way to care for their cats. Aggressive marketing makes a pet parent feel good about forking over exorbitant sums of money for food that a veterinarian or nutritionist gets a commission on selling. The truth is that many prescription diets are chock full of high-glycemic, cheap ingredients sold at a premium.

 

Writing Their Own Rules: The Problem With The Cat Food Industry

 Americans are discovering that the lack of adequate regulation has resulted in food that may be slowly killing their beloved pets, whether through chronic diseases, allergies, malnourishment, or dehydration.

We are not completely against commercial food, as there are many great products on the market. Many companies are finally meeting the demands of pet parents who want to feed their cats a healthier diet. Feeding your cat a more appropriate diet won’t have to break the bank either.

However, it hasn’t always been that way. Public opinion has been so heavily influenced by the pet food industry that most pet owners no longer consider feeding the kind of diet kitties in the past enjoyed and thrived on. Scraps, raw ingredients, and raw diets are seen with suspicion and maligned as harmful, risky, or “people food” and not suitable for animals.

Few other industries in the US have such obvious and detrimental conflicts of interest. Pet food regulation in the US is somewhat convoluted. The FDA advises but ultimately tasks the American Association of Feed Control Officials (AAFCO) with issuing regulations. The AAFCO is a private corporation and you have to pay a significant amount of money to access the legal definitions they write. AAFCO is heavily influenced and controlled by the pet food industry and the results are clear. Don’t believe us? Just look at who’s attending the AAFCO meetings. Over half of the attendees at the most recent meeting as of this writing were employees of pet food manufacturers.

  • The cat food industry heavily influences or outright subsidizes the US veterinary education system’s nutritional training.
  • Regulations, government oversight and approval processes for cat food are pretty much written by the companies and entities who make it.
  • The industry has a vested interest in continuing to push grain-based cat food vs. meeting the science-based nutritional needs of cats

 The pet food industry is exploited by the manufacturing and agricultural industry. Corporations that produce human food produce incredible amounts of waste. As an example, nearly 50% of a cow is considered “waste” and not fit for human consumption. The pet food industry provides a market for that waste. Animals have long eaten leftovers from human food, and industrializing the process makes sense.

Unfortunately, the industry operates under little regulation with heavy influence over veterinary education. Billions of dollars sunk into marketing secure the public’s perception that what’s on the brightly colored bags is what’s going into their pets’ bowls. The ones who suffer are the cats and dogs being fed questionable food by pet parents who don’t know any better.

A History Of Bad, Unregulated Food

When we think of bad food, it might seem like it would affect our cats immediately in ways that are easy to see. But animals are tough, and cats have managed to make it work, living on substandard cat food for decades even though their bodies have not evolved to digest it. Unfortunately, there have been consequences. Modern pet food has contributed to a marked rise in degenerative disease, urinary problems, cancer, metabolic stress, and inflammation.

Profits have long driven what’s in cat food. Most cat food (yes, even the expensive stuff!) is unhealthy, including:

  • Grain-based food, causing obesity and diabetes
  • Grain-free, high glycemic diets
  • Alternative protein (such as legume) sources for “vegetarian” pet diets

The commercial pet food industry is one of the newest in the US, believe it or not. Alongside advances in food preservation and processed food for humans came mass-produced pet food. Primarily sourced from whatever was left over after human food had been made, pet food evolved from biscuits and canned food to dry food. Most cats lived on scraps, and outside prey such as mice, birds, small mammals and insects.

Towards the middle of the 20th century, pet food manufactured using the extrusion method became popular. This process involves cooking everything together, mushing it out through an extruder to shape it, baking, and eventually coating the “kibbles” in flavorings and nutrients that were lost during the baking process.  Aggressive marketing and information campaigns by major pet food manufacturers soon led us to believe that dry food is best for our cats, and any “people food” is dangerous for them. This has been the mindset ever since. It was around this same time frame that American humans began consuming large quantities of processed, artificial foods, and have been suffering ever since from a litany of “epidemics” that resulted.


Special Dietary Needs

 Diets for Gastrointestinal & Urinary Health

Kidney disease is sadly common in cats, especially older pets.  A renal diet high in fat (including omega-3 fatty acids) and low in protein and phosphorus can extend the life of a geriatric cat, although there are currently no therapeutic standards for this kind of diet.  While healthy cats require high amounts of quality protein, processing the resulting nitrogenous waste products stresses the kidneys of a cat with chronic kidney disease.  Too much phosphorus can crystalize in body tissues, causing damage.  The lower protein content must be balanced with higher fat to provide sufficient energy.  Fat can also make a low-protein diet more appealing to a cat.

Cats with hepatic encephalopathy (a liver dysfunction) are especially vulnerable to malnutrition. A food composed of high quality protein with sufficient taurine and arginine can be essential for animals with this condition.

Cats with digestive health issues benefit from a diet that includes adequate fiber, antioxidants, fatty acids, and pre- and probiotics.  Gastrointestinal issues can be mitigated by diets containing more easily digested compounds.  Fructooligosaccharides (FOS) appear to result in a balance of more easily metabolized fatty acids in the digestive tract.  Feeding smaller portions more frequently is also beneficial in addressing GI problems.

Urinary health foods are specially designed to have a reduced pH and low amounts of magnesium and phosphorus to eliminate or prevent kidney stones.

Some cat foods are specifically formulated to reduce the incidence of hairballs.  These foods typically contain higher amounts of fiber to move ingested hair through the digestive system.  They may also incorporate enzymes to reduce the accumulation of hair and formation of hairballs in the stomach.

Diets for High Energy: Pregnancy, Lactation, and Weight Gain

Certain cats, including kittens, pregnant or lactating females, or cats who have been sick, benefit most from a high energy food.  Such foods rely on a higher fat content (20% dry matter), as fat provides more energy than either carbohydrates or proteins.  Pregnancy puts significant strain on a cat’s body.  A pregnant female may lose as much as 38% of her body weight by the time her kittens are born.  Providing a more energy dense food (high-fat and easily digestible) is preferable to simply providing extra food.  Mature cats (typically over 12 or 13 years of age) may also require a higher-energy diet, possibly due to less efficient digestion of fats and proteins, if they are in danger of becoming underweight.   Cats recovering from surgery or serious illness will require a high-energy (high in proteins and fat), palatable, and easily digestible diet.  This reduces the amount of food the cat must consume to maintain adequate energy for healing, an important consideration where the cat’s desire to eat may be low.

Diets for Weight Loss

 Maintaining a cat’s energy balance helps avoid excessive weight gain.  A weight control diet is lower energy (less calorie-dense) and higher in fiber. Increased soluble and fermentable fibers like fructooligosaccharides (FOS) and mannonoligosaccharides (MOS) promote healthy eating rates.  Insoluble fibers regulate appetite.  Cellulose, psyllium, barley, and beets are all common fiber sources found in cat foods.  Higher protein content and lower fat is important in maintaining a healthy metabolism and lean muscle mass.  L-carnitine, an amino acid derived from animal proteins, is another nutrient specifically added to a weight control diet to boost breakdown of fatty acids and maintain healthy metabolism.

 Diets for Diabetic Cats

Foods for diabetic cats are created with fewer carbohydrates (which is a good idea for cats overall).  Note that for a cat being treated with insulin, reducing carbohydrates in your cat’s diet may require an immediate adjustment to the insulin dosage to avoid a low blood sugar crisis.


 Summary:

 Choosing the right food for your kitty can go a long way towards maintaining her good health. There are many ways to feed your cat a nutritious diet appropriate for her species. Knowing your cat’s nutritional requirements will make it much easier to decide how and what you’ll feed her.

With renewed interest in the well-being of our pets, manufacturers are rising to meet the demand for high-quality food. There are many great options out there to help make feeding your cat nutritious food convenient.
