Vegan and vegetarian diets can work wonders for human well being however suppose twice earlier than imposing your dietary preferences in your cat. Protein is a important element of a balanced feline food regimen and a few varieties of protein are extra precious for cats than others.
On this information, we’ll discuss concerning the position protein performs in a feline food regimen and talk about why protein from animal sources is probably the most species-appropriate choice. We’ll additionally supply suggestions for studying cat meals labels that can assist you select the very best food regimen on your cat.
Let’s begin with an outline of the dietary necessities of cats.
Protein Is Simply One Piece of the Puzzle
Of the six courses of vitamins—protein, fats, carbohydrates, nutritional vitamins, minerals, and water—the physique makes use of the primary three as power sources. Relying on their anatomy and physiology, totally different species rely extra closely on sure vitamins than others.
Cats, for instance, rely totally on protein and fats—they’ve a really low dietary requirement for carbohydrates.
Within the wild, a cat would get all of the amino acids, fatty acids, nutritional vitamins, and minerals they want by consuming entire prey. A complete-prey feline food regimen consists of muscle meat, organs, and bone in addition to the abdomen contents of the prey, which seemingly include small quantities of plant matter.
Some industrial cat meals mimic an entire prey food regimen extra carefully than others, relying on the substances, however they need to meet sure minimal dietary necessities set by the Affiliation of American Feed Management Officers (AAFCO) to be thought of nutritionally full.
Together with particular ranges of key micronutrients, an entire and balanced industrial food regimen for grownup cats incorporates a minimal of 9% crude fats and 26% crude protein, each measured as dry matter. Cat meals formulated for kittens and pregnant or lactating feminine cats should include a minimal of 30% dry matter protein.
Animal Protein vs. Plant Protein
Proteins are made up of chains of amino acids that the physique makes use of to develop and preserve wholesome muscle tissues, bones, and pores and skin.
In line with Dr. Jo Myers, DVM, a veterinarian at Vetster, “Cats, people, and different animals have totally different protein constructing blocks they will manufacture themselves, whereas different protein constructing blocks should come from their diets.”
Cats require 22 totally different amino acids, ten of which they will synthesize from different chemical substances within the physique. The remaining 11, known as important amino acids, should come from the cat’s food regimen. All mammals share the necessity for 9 important amino acids however cats require two extra: taurine and arginine.
The important amino acids cats want embody:
- Taurine
- Arginine
- Histidine
- Isoleucine
- Leucine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Valine
Meals that include all of the important amino acids an animal wants are known as an entire protein supply. Many meals include amino acids however solely animal proteins—issues like beef, hen, eggs, and fish—are thought of full proteins for cats. Plant proteins don’t include taurine or arginine, each of that are essential on your cat’s well being.
If cats don’t get these important amino acids from their food regimen, they may turn into poor. The kind and severity of ensuing signs will rely on which amino acids they’re lacking, and by how a lot, however dietary deficiencies can result in extreme illness.
However can plant protein nonetheless be precious for cats? Dr. Raymond Spragley, DVM, CVA, CCRT, says, “Plant protein might be useful when it comes to fulfilling cats’ total want for protein however can’t fulfill their dietary wants by itself.”
In different phrases, plant proteins can enhance the overall protein content material of a cat meals product. Nonetheless, as Dr. Spragley feedback, for the meals to be thought of nutritionally full, it “have to be supplemented with animal protein to supply cats with the amino acids and nutritional vitamins they should survive and thrive.”
Let’s delve additional into this idea with an instance.
The Drawback With Plant Protein in Pet Meals
Many pet homeowners don’t look past the product title when purchasing for cat meals. Even the assured evaluation on the label doesn’t at all times inform you the entire story. A food regimen labeled as a high-protein cat meals could also be increased in protein than the typical product however you’d must delve a bit of deeper to seek out out the place that protein comes from.
For instance, throughout a current journey to the pet retailer, I picked up a bag of cat meals from a model I didn’t acknowledge. The product title implied it was a chicken-based formulation and I used to be impressed by the protein content material listed within the assured evaluation.
Upon searching the checklist of substances, nonetheless, I noticed an issue.
The primary ingredient listed was hen. Nice! Brown rice got here subsequent. So far as carbohydrates in cat meals go, I want brown rice over starchier choices like tapioca or hard-to-digest peas or different legumes. The issue wasn’t the carbohydrates—it was the plant protein concentrates. Pea protein and potato protein made up substances quantity three and 4.
In line with Dr. Paola Cuevas, MVZ, a veterinarian and animal behaviorist, “Plant protein concentrates are processed to take away the starchy or carbohydrate parts and extrude the protein parts of vegetation.” Pet meals producers usually use them to inflate the overall protein content material of the product.
Extra protein in cat meals is an efficient factor. However the advantage of further protein solely goes to date when plant-based proteins overshadow or act as a alternative for extra biologically precious animal proteins.
What it comes all the way down to is that this: cats are obligate meat-eaters, so meat-based diets are merely extra acceptable for his or her biology, anatomy, and vitamin than plant-based diets.
Can Cats Survive on a Plant-Primarily based Weight-reduction plan?

By now we’ve established {that a} food regimen wealthy in animal protein is good for cats, however can a cat survive on a plant-based food regimen? Is the vegan food regimen a viable choice for cats? To reply this query, we have to do not forget that cats are obligate carnivores.
A food regimen for obligate carnivores, feedback Dr. Neus Torrent, DVM, an animal nutritionist for Outside Bengal, requires vitamins discovered solely in animal flesh. “Whereas cats may be capable of ingest small quantities of plant matter,” he says, “they lack the required physiology required to totally digest it.”
Dr. Meyers provides a proof that helps conceptualize the organic distinction between herbivores and carnivores.
She describes herbivores as micro organism farmers, explaining that, “The plant supplies they ingest are used to feed giant populations of micro organism of their digestive tracts, which they subsequently digest and obtain vitamins from.”
Each herbivores and omnivores, she notes, have grinding enamel to assist break down vegetation earlier than it enters the digestive tract to streamline this course of. A fast peek into your cat’s mouth will reveal a key attribute that identifies them as a carnivore: their sharp enamel.
A cat’s enamel are supposed for tearing meat, not grinding vegetation. Greater than that, nonetheless, a cat’s digestive tract isn’t designed to course of plant matter.
“The feline digestive tract is small and doesn’t have a number of stomachs, like cows and sheep,” says Dr. Meyers. “In flip, cats can’t farm micro organism… Their intestines aren’t designed to effectively take in plant proteins and different vitamins, leaving most plant vitamins unavailable to them.”
Dr. Cuevas notes that producers of plant-based diets for pets attempt to get round this downside by including artificial variations of important vitamins like vitamin A and niacin and the amino acids taurine, arginine, and lysine. Even so, she says, “Research have proven that vegan cat diets are poor within the vitamins a cat must thrive when in comparison with the AAFCO minimal requirements.”
To summarize, a cat may be capable of survive on a supplemented plant-based food regimen however it could not thrive. A number of of the veterinarians I consulted commented that long-term feeding of plant-based diets can predispose cats to severe well being issues like diabetes and cardiomyopathy.
Suggestions for Deciphering Cat Meals Labels
If you wish to feed your cat a biologically acceptable food regimen, perform some research first—the product title doesn’t inform the entire story. As Dr. Myers says, “Studying cat meals labels isn’t as simple or easy as you may suppose, and it may be troublesome to separate reality from fiction.”
Right here are some things to think about when studying a cat meals label:
- The assured evaluation normally lists vitamins on an “as-fed” foundation, which incorporates the water content material. You might have to convert the values to dry matter if you wish to make an correct comparability between merchandise.
- Simply because an animal ingredient seems within the product title doesn’t imply it’s the primary ingredient. Double-check the checklist of substances and keep in mind they’re organized in descending order by weight.
- Pet meals producers usually “break up” plant-based substances to decrease their place on the substances checklist. For instance, a hen and potato cat meals may include 18% hen and 30% potato. Nonetheless, by splitting the potato into potato flour, potato starch, and potato protein, the hen will seem on the high of the checklist.
- Plant proteins aren’t at all times listed within the type of a focus. Components like corn gluten meal, soybean meal, and peas can add considerably to a cat meals’s complete protein composition.
With so many cat meals merchandise on the market, it could appear to be an inconceivable process to type the nice from the dangerous. A little analysis goes a good distance, nonetheless, and recalling your cat’s biology as a carnivore will provide help to make a wholesome choice in your cat’s behalf.
Often Requested Questions

Is it merciless to feed your cat a plant-based food regimen?
Sure, it’s merciless to power an unnatural food regimen on a pet.
