I also feed my cats Felidae but I mix in some Nutro Natural Complete Care Weight Management Formula in it too. After taking Sky to the vets today, I learned that Sky is gaining too much weight so I need to put him on a diet. A cup of Felidae has 543kcal so that's quiet a lot. I'm supposed to only feed Sky 300 calories a day. On the bag of Felidae it recommends that you only feed your cat 1/4 cup for each 5lbs. of body weight. So if Toby is 10lbs., he only needs 1/2 cup a day which isn't much. So you might think that Felidae costs more but it should last you longer than your other brand because you don't need to feed your cats as much of it.

My cats still seem to prefer the Nutro over the Felidae but I'm not willing to give up because I really like the quality of this food. Good luck.
