Back when I used to go to Weight Watchers our instructor used to tell us you can get fat eating anything, if you eat enough of it.
Absolutely true.
I just saw one of my adoptees who is only 8 months old and is WAY too fat! I have lectured the adopters about instituting portion control now....not later.
At 8 months of age he weighs 10.75 pounds and is not a large-boned cat.
My Calvin is a bit chubby and he eats raw but is not one to expend very many calories so....yes...any living creature can pack on the fat pounds if calories in are greater than calories out.
When a cat is still growing, I am more careful when restricting calories but I will still do it as long as I am feeding a reasonably high quality diet.
I am going to try to find the time to work on my Feline Obesity page because when I first wrote it, I did not focus heavily enough on percentage of calories from protein versus fat and Janet is so right....there is far too much fat in many of the 'higher end' diets.
Dr. Zoran just came out with an Obesity article where she really pushed for at least 45% of calories from protein.
That said, I have had/seen many cats lose weight successfully (defined as slow weight loss while maintaining muscle mass and energy level) on canned Wellness which is only 30-37% protein.
Keep in mind that you can bump up the protein calories with plain, lean meat (chicken or turkey but chicken tends to be lower in fat than turkey) but make sure that it does not comprise more than 15% of the total calories since plain meat is unbalanced....ie....there is no calcium in it, to speak of.
If you feed this lean meat in the form of chunks, you will be helping their oral health also.
