Lily will eat anything, including curry. I have to be careful not to let her near it, because it has a lot of onion (well mine do!) She also chases dogs. I don't think she realises she's a cat!
I've just found something that gives a reason not to give cats cold food. It may upset their stomach, apparently, but I think that's really just for cats with delicate stomachs, like old cats, or very young kittens, so I don't think I'll worry too much.
