Thank you Katrina. I had him on the Science Diet Light for a bit but tried some other light foods that were a little less expensive. I just need to quit giving him to much when I feed him, I think.
I'll try to dispel some myths about feeding cats. Cats are obligate carnivores that have evolved eating prey and have no requirement for carbohydrates. Therefore, cats are adapted for higher utilization of protein and lower utilization of carbohydrates. Cats preferentially use protein as an energy source and store the excess energy
from the diet in the form of carbohydrates as fat. Obese cats fed low fat, high fiber weight loss diets may experience weight loss, however, unless protein levels are higher than typical diets, this will be at the expense of lean body mass. Preservation of lean muscle mass is not only essential to overall health but is one of the key determinants of basal metabolism. Loss of muscle mass leads to increased morbidity and during weight loss can result in metabolic changes that make successful weight loss extremely difficult.
Because carbohydrates are necessary for the production of commercial dry diets, all dry diets will contain at least 15 to 20% carbohydrate. Some canned foods contain extremely low concentrations of carbs (less than 6% on a dry matter basis). Dry cat foods are not detrimental to cats when fed appropriately. However, most people feed dry food because they can be provided free choice for the owners convenience.
Calorie control is essential. Feed foods that are less calorie dense (canned food). A cat in ideal body condition and weighing 10 to 11 lbs. should eat approx. 200 kcal per day, and an obese cat will require significantly less (up to 60%) until an optimum body weight is reached. Because of this extreme reduction in caloric intake, it is vital that the diet contain high quality ingredients and enough protein to prevent protein malnutrition. Cats should be fed their recommended caloric intake in 2 or 3 divided meals, and free choice feeding should be eliminated. 45% protein of metabolizable energy is the minimum required to optimize fat loss and preserve muscle mass.
A good choice is Hills Prescription m/d canned. A cat that should weigh about 10 lbs can recieve 1 to 1 1/4 5.5oz can daily (divided into 3 feedings).
Avoid treats and snacks outside of the diet and increase exercise (a laser pointer works well for many sedentary cats). Good luck.
