My cats get all the cooked meats now and then, and some of them raw.
They get a very small amount of cheese at times, often because they steal it from us.
You can give them chicken necks, raw egg yolks. There are a bunch of things you can give.
Check out the Raw/BARF diet, basically everything they have in there as a meal, you can give as a healthy snack to a cat on a canned/dry diet.
