Yeah, to be clear, you should not feed your cat a Vegan diet. Cats are obligate carnivores. Synthetic Taurine has made vegan catfood somewhat more viable, but cats don’t just need Taurine from prey. They need several vitamins, amino acids, and fatty acids from animal protein to survive. Beyond that, their digestive tract isn’t very efficient at digesting plant matter, so even if these foods have the nutritional value they need, they might not be absorbing it. Also, a lot of these products seem to be made from grains and other carb heavy products, and cats need a very low carb, high protein diet. If you want to completely divest from the meat industry, you simply shouldn’t own a cat.
That being said, Vegan catfood products are on the market, so whether or not they are good for cats, they have been approved by several regulating bodies. You can claim that they’re unsafe (I certainly do), but having an admin nuke a comment section for claiming otherwise is a huge overreaction. It would be like going into a vape community and banning accounts that claimed vaping is safer than smoking; it probably isn’t, but I don’t need admins deciding who gets to have discourse about that.
Finally, I’m also not a fan of dead cats, but if you’re dumb enough to take veterinary advice from an internet vegan group, you’re probably too dumb to keep a cat alive anyway.
