Besides processed cat foods (dry and canned), what healthful items can I feed my cat? Eggs--cooked or not? Chicken parts (where to get hormone/ antibiotic-free chicken)? Any fruits? Etc...
For treats mine occassionally get hard boiled eggs, cottage cheese, cooked chicken, beef or pork (the same meat I eat but without seasonings), chick peas & green peas.
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.
steamed green beans chopped up, steamed squash, raw egg yolks no whites though baked potato with butter and plain yogurt and their absolute favorite, smoked oysters and dried fish.
