Obesity is one of the leading health problems cats face. If your cat is more than 20 percent over his ideal body weight, he is at risk for heart and liver disease, diabetes, arthritis, and an increased surgical/anesthesia risk (a lot like humans).
Adult cats typically weigh between 9 and 11 pounds, have very little fat over their ribs, and a pronounced waist.
Obesity results when your cat takes in more calories than he burns. To help prevent obesity and the health problems associated with it, be sure to schedule a veterinarian visit to rule out any health problems that may be contributing to obesity.
It suggested that you feed your cat only once a day - preferably in the evening - and leave the dish out for 30 minutes only. You can also reduce the amount of food by one quarter.
Also, make sure your cat gets plenty of exercise. Encouraging him/her to play is one of the best methods. Get your cat moving with his/her favorite toy. Obesity is a very preventable problem. Keep your cat thin and he'll reward you with years of health, happiness, and joy.
