      They need an appropriate array of vitamins, nutrients, and calories to stay alive. The way they do this naturally is to eat meat, but it’s not the meat specifically that they need.

        They require meat proteins to live, plain and simple.

        It’s even law in some countries that classifies feeding cats a purely vegan diet is animal cruelty.

          meat proteins

          Proteins are chains of amino acids. There are probably proteins specific to animal muscle, but misguided legislation notwithstanding it’s the amino acids that are nutritionally required, not any specific protein configuration of those animos, and you can get those from a massive array of non-animal sources.

            Taurine and arginine are amino acids, building blocks for proteins, not proteins themselves. Animo acids are quite ubiquitous across life, not specific to any one type of life. eg Plants contain both taurine and arginine.

              thanks for the additional information

              i remember reading that plants can’t supply enough taurin. Luckily it seems easy to synthesize (that’s how we have redbull &c

      I don’t know much about cats but this seems reasonable: https://cats.com/vegan-cat-food

      Vegan cat food isn’t natural. It’s not normal. Cats will always want to kill and eat other animals. And yet—our cats aren’t natural.

      Dr. Jennifer Coates, says “While it may be possible for a veterinary nutritionist to design a “vegan” recipe for cats that wouldn’t lead to disease, it would have to contain large amounts of nutritional supplements, some of which would probably have animal origins, raising the question of whether that diet would truly be vegan. Even more importantly, the goal in feeding pets is not simply to avoid diet-related illness but to promote optimal health and wellbeing. I sincerely doubt this is possible with vegan cat food.”
