Would you know if your kitty needed to slim down? Fat cats are so common that you might not even realize yours is on the portly side. But overweight and obese cats now outnumber those at a healthy weight, and vets are seeing more super-obese cats, too.
“The problem for us is we like to spoil our cats, and the cats like to eat, so it’s easy to overfeed a little bit,” says Philip J. Shanker, DVM, owner of The Cat Hospital in Campbell, CA. 

It’s something to take seriously. Even just a couple of extra pounds can make your pet more likely to get some health problems such as type 2 diabetes and make others, like arthritis, worse. It can even keep them from grooming themselves properly. Keeping off excess weight should lead to a healthier, happier cat.

Ideal Weight for Cats

Most domestic cats should weigh about 10 pounds, though that can vary by breed and frame. A Siamese cat may weigh as few as 5 pounds, while a Maine Coon can be 25 pounds and healthy.

Your vet can let you know if your cat is overweight, but there are some signs you can look for on your own, says Melissa Mustillo, DVM, a veterinarian at A Cat Clinic in Maryland.
“Cats should have that hourglass figure when you’re looking down at them, they shouldn’t have a saggy belly hanging down, and you should be able to feel their ribs,” she says.

How to Keep the Pounds Off

Vets say that cats’ weight gain usually comes down to the type and quantity of food they’re fed, along with plain old boredom.

“When they’re bored, they think, ‘I might as well go eat. … Oh, look there’s no food in my bowl, I’m going to bother mom for more food,’” Mustillo says.

And when they whine, many owners give in to keep their pets happy.

But it is possible to prevent or curb weight gain:

• Replace dry food with canned, which tends to have more protein and fewer carbohydrates. Canned food is also a good way to set distinct mealtimes for your pet. Many cats gain weight when owners leave out a bowl of dry kibble so they can eat all day long.
• Cut back on treats. Cats do just as well with other rewards, like playtime with you.
• Make your cat work for its food. Vets have found cats are healthier and calmer when their owners use “food puzzles,” which the cat must roll or manipulate to get treats out of. You can hide some in the compartments of a wine box or cut one or more small holes in a plastic bottle and fill it with kibbles. The puzzles slow down their eating while tapping into their natural instincts to hunt and forage.
• If you have more than one cat, you may need to feed the overweight one in a separate room or put the healthy-weight cat’s food up high where the fat cat can’t go.
