Checkout this article. It's Atkins for cats. Should I try this on my 16 pound Larry?
Although right now I started to buy one brand of catfood that fits what we need for him. It's Purina One Hairball & Overweight formula. I had not seen any other brand that combined both of those in one package. Until thenI was having to buy 2 different bags and mix them: one for overweight cats and one for hairballs.
I think I might just try the Purina One for a while. Both cats like it, so it works so far. They are kinda picky. They just better keep making it. Maybe I should send them a letter knowing how much I like serving this to my cats.
