Any kind of meat is OK: beef, pork, chicken, turkey. With fish, it should never be fed raw. There is something present in fish that can antagonize vitamin E usage. Cats aren't supposed to eat fish anyway. Cats evolved as a desert predator, and their ancestor is the African wildcat. That said, if I had some cooked fish, I would give my cats a couple of bites. But it's not species-correct for cats to have a fish-heavy diet, and I don't recommend it.
