You are correct. I'm mostly vegetarian (I eat fish), but I won't do that to a cat. They need meat for health, and not doing so is cruelty.
I truly wish that these folks would give the cats away to someone that can feed them properly and invest in a vegetarian pet that fits their lifestyle: Birds, iguana, and so on.
I used to form lines with cat food. Looked a bit like farming.
Birds then would try to eat the remains, only to become additional cat food.
