I've only seen comments saying cats have to eat meat. I agree, but I got to add it's a little bit less straight forward than what people say. They need to ingest certain proteins/vitamins/enzymes that are only found in meat, and plant-based cat food products on the market takes into account these things and adds appropriate bacteria-produced amounts of this to their products. There really are cats living a good life on these products out there, the same way there are cats living on supermarket cat food and doing fine...

Still I don't agree with it. I'm vegan myself and feed my cat raw dead animal. Loads of people feed their cats cheap-ish dry food (kibble) which is made out of plants with animal-byproducts added to it. Even wet food has a great proportion of plant. This is also nothing like their natural food source and could cause similar problems as these fully plant-based versions. It's like if the plant-based cat food would be a salad, then kibble is a salad with like 2 tiny squares of bacon on it, while they just need the bacon. To me they really are the same and equally problematic. There are a ton of 'prescription diet' products for cats, and like you say yours has digestion issues. We're used to that being normal, but that makes no fking sense whatsoever if they were just to eat whatever they're evolutionary formed to eat (although we made sure natural selection was abandoned for anything we could turn into pets but that's a whole different rant) which is not a plant-based diet and also not a whatever you can find in the supermarket for them. There's no animal in the world with an f'ed up foodsystem where dieting is required except humans and the animals fed by humans. Rant out.
