I'm not sure what number to go by. Cincy also needs to loose weight and we had been feeding her Californaia Natural Lamb and Rice Reduced Calorie. It is 8% fat and 317 cal/cup.

Cincy is having problems with her kidneys and our vet believe this food is too rich for her to digest. He feels she needs more "fillers" in her diet...her body can not break down the higher quality food. So, at his recomendations we are trying Hill's Science Diet Light. It is 6% fat and 295 cal/cup I read the ingredients and cringe, but it is what he feels we need to try to get her better, so i'm trying it. We'll see what happens.
