Poor Meow, the obese cat, may have been the victim of nutritional misinformation. His special “dry cat food diet” was probably loaded with carbohydrates!
When my house cat started getting fat a couple of years ago, the vet advised feeding her a half can of high protein canned food twice a day. She lost the extra pounds and has been healthy ever since. The vet told me that cats are just like people. They can’t eat too many carbs. Wild cats live almost exclusively on meat, and they eat their food when they catch it, so two daily feedings mimic the natural diet better than one.
