Hi quality dry food, and wet food ONLY as treats. I only give them a tablespoon or even a little less, maybe once a week. I haven't ever heard that they "need" wet food.

I do give Tex (thin thin vomit man) wet food nearly daily, right after he takes his throwup medicene. He eats it more readily, and he totally needs all the calories he can get. Boy do the others put up a fuss though.
