I buy my cats Eukanuba, because last time I checked, the first four ingredients were meat, and no other cat foods had this. The two of them split a can of food every other day (one throws up if he gets more.) One is a big cat structurally, one is very dainty, but neither of them are overweight.
I think you are on the right track! Especially cats, who are even more carnivorous than dogs are.
Speaking of dogs, does anyone but me get indignant over that dog food commercial that brags about being full of "healthy grains and vegetables!"
Oh, yes, everyone knows dogs love that. Farmers have a terrible time keeping their dogs out of the wheat field and the tomato patch...
