Cats are obligate carnivores in the wild. This just means they have dietary needs that would normally require meat. But we can make vegan, synthetic food that meets these needs. In fact, studies have shown that cats on vegan diets tend to be healthier if anything.

I don't know enough about that topic to argue for or against which is not what I'm trying to argue

Show me a scientific study that proves this. If you can say it with confidence, it should be no trouble at all for you to prove it. I, on the other hand, am lazy and don't care all that much, so I want the people confidently stating opinions to share their research to save me effort.

they can't be vegan as that is an ethical choice. they can be plant based and live a perfectly normal life.

tell me where you disagree with this guy:
