also, yes, cats need high protein, low fat. But a quality fat, that has plenty of cholesterol, saturated fats and stearates. Omega 3s like in egg yolk make their fur super pretty, so I figure probably fish is a really suitable food for them. Preferably whole, just gut the fish and slap it down and let nature take its course. Rodents also, same thing, just gut them and off they go. All the collagen in the skin is good for them too.
