I have a 17 year old (indoor) cat that is in great health. Active, attentive, etc. Good coat and appetite. Vet says he's doing great. All numbers are right (though kidney function may be slightly suspect). Six years ago he was pushing 14 lbs, and probably overweight. Now he's 9 lbs, and could use some more flesh. So the question is, what's the right way to help him gain some weight? The usual answer is to feed kitten chow, but I'm kind of mystified. His regular diet is Purina One, which is 37% protein, and 13% fat. The basic kitten chow is almost the same. Huh? Now, Hills is noticeably less nutritious, with 28% protein, and bit more fat.
Now canned food is dramatically lower in fat and protein, but I assume that's because cats eat more of it. The protein in those is a factor of three lower, and the fat is about a factor of ten lower than the dry food.
So I'd appreciate suggestions of cat foods that have higher levels of protein AND fat. I mean REAL vet-approved cat foods. Maybe a recommendation for a particular affordable kitten chow that has decently high protein and fat numbers?
