Can a vegan diet for a cat be acceptable? — 7 Comments

  1. A vegan dry food is apt to cause serious urinary tract issues in cats–something PETA knows very well. There is a long list of nutrients cats need (besides taurine) that aren’t provided by a vegan diet. I have seen some pretty sick cats who were forced to eat a vegan diet. Don’t do it.

  2. Dr Pete Wedderburn has a great point. For example: Protein is protein, right?

    WRONG! Plant protein is molecularly different from animal protein. This results in inadequate nutrition for the carnivorous pet.

    Moral of the story? Feed your pet a species specific diet and forego your opinion. You don’t want me to force my opinion on you, so why are you forcing yours on someone who can’t speak human?

  3. “It’s just bits and pieces of different animals which is absolutely revolting. There is no way out feed my cat that”.

    Without getting into the what the hell is in that can of cat food cats that eat small prey eat the whole animal not just the choice cuts. So we need to get beyond our often warped sense that it’s OK to kill an animal for food but be repulsed by 3/4 of it.
    As to a vegan diet for your cat as stated before if you can’t handle the tins of meat get a different pet. This is humans trying to modify a well developed species to their needs not the cats. Poor stewardship at it’s best.

  4. Interesting discussion. I can thoroughly understand the nutrient theory. There is one point that enters my mind concerning a feline vegan diet. It is documented that cats, as in other carnivores, have a shorter intestinal length, in relation to body length, than do omnivores and herbivores. The ratio is said to be 4:1. However they have a greater absorptive capacity, making digestion of fibers and starches only 10% less efficient. Obviously the majority of cats left to their own devices will choose live prey, which greatly contributes to their daily water requirements. I do not feel conclusive either way concerning this topic.


    • Thanks Frances. I agree it is a tricky subjects to discuss. Perhaps that is why I’m discussing it. I, too, and ambivalent about whether a vegan diet is acceptable to a cat even if it is manufactured to a high standard and contains all the required nutrients. I just feel that people should not say such a diet is completely hopeless and useless. I don’t think that it is as black-and-white as that. Perhaps that is the underlying point that I wish to make.

  5. Provocative, yes. Nutritionally sound? Not so much. Cat food in supermarkets are just crap; there’s no getting around it. That’s why cats should be given higher quality food, without all of the chemicals, bone meal, etc. I read EVERYTHING on the labels, including percentages of ingredients. I am not convinced that a vegan diet has been proven to be sufficiently acceptable to cats nutrition-wise. It’s only been a couple years of testing – not long enough for my own cats’ diet. Mine are fed both wet and dry. The wet is a high quality brand, without chemicals and junk. The dry is a nutritionally sound, low fat brand (not found in local green grocers/supermarkets) and is limited in feeding. Both of my cats, ages nine and ten still behave as if they’re kittens, even the one who’s FIV+. That’s proof enough for me.
