My cat is one year and a half, and when she was a kitten, we used to give her a range of dry and wet cat food, as recommended by our vet. But recently we've noticed that every time we give her wet cat food, she gets diarrhoea. So we stopped giving her wet food, and tried to change the type of dry food we give her but any other brand of dry food we give her makes her throw it up, like its been chewed, swallowed, and brought back up.

I don t think she s sick, and she's fine when we just give her regular dry food, but what I m basically trying to ask is is it okay to give her the same kind of food everyday?
