Weight control in your cat is dependent both on the amount of calories your cat eats and the percent protein in the food.  
 


High carbohydrate food (dry foods with only 35% protein or wet food with only 8% protein) cause your cat to produce more insulin and drive the carbohydrates into the fat pads even if the total caloric intake is low. Not all cats have this problem but if your cat is fat you need to use a food high in protein and low in calories to lower its body weight. The table below lists the amount of high protein food that is needed to achieve a desired weight. Failure to control the weight of your cat will predispose it to diabetes.
