If your cat is fat, he might have an even bigger problem. The rate of type 2 diabetes among pets—particularly cats—is soaring, reports the Chicago Tribune. Experts aren't in total agreement about why, but in general they think that our furry feline companions are developing the disease for the same reasons we are: sedentary lifestyles and lots of refined foods.
In the case of cats, that food is dry kibble, which is high in carbs and low in protein. Because cats are carnivores, meaning they'd eat other animals instead of plants, many vets now recommend that cats eat high-protein canned food. Owners, meanwhile, are encouraged to get their tubby toms off the couch as much as possible. If nothing else, move the food dish every few days.
