Indoor Living Changes Cat Food Needs
By Elizabeth Parker
With food and water served daily, comfortable furniture
to curl up on and no immediate threats to safety,
indoor cats enjoy a life that outdoor felines, and even
some people, seem to envy. But the good life can be
hazardous for cats if it leads to weight gain. When left
unchecked, those extra pounds can cause serious
“Research indicates overweight cats have two times
the risk of having skin disease, four times the risk of
having diabetes and five times the risk of having
lameness,” says Ann Hohenhaus, DMV, at the Animal
Medical Center in New York City.
Experts, however, are quick to add that your cat is far safer indoors, so it’s imperative
that you provide opportunities for daily exercise as well as the right kind of food to help
your indoor pet maintain a healthy weight.
Is Your Cat Too Fat?
“Cats are like old men,” says Jessica Braun, DVM, owner of Animal Health Center of Hays,
in Kansas. “All the extra weight goes to the belly.” Although your veterinarian can tell you
the best weight for your kitty, a cat with a big tummy is most likely overweight. These
days, fat cats are common. Nearly half of all the cats that come to Dr. Hohenhaus’s
medical center are overweight or obese. “Almost all the indoor cats I see are
overweight,” says Dr. Braun.
Male cats tend to be heavier in general, but there are plenty of hefty female felines, too.
Both spaying and neutering can be factors, since they may reduce certain hormone levels
and can lead to some decreased activity. The benefits of spaying and neutering,
however, far outweigh any side effects; the primary reason that cats carry extra pounds
has nothing whatsoever to do with a surgery. Cats are usually fat because they’re being
overfed or not consuming the right vittles for their particular lifestyle.
“I think it’s better to feed a cat twice a day,” advises Dr. Braun, who explains that when
given unlimited food, cats will eat more. “Cats are nibblers,” she says. “Whenever you
leave dried food out, 80 percent to 90 percent of cats will eat too much.” You can
control your cat’s weight by limiting food but also by offering food that targets an indoor
The Right Food for Indoor Cats
If your cat is looking a bit hefty around the middle, try feeding one of the new
commercially available foods that are specially made to address the particular health
challenges of indoor cats. Some contain the nutrient called L-carnitine, which converts
fatty acids to energy, thus helping weight loss. Lower in fat and calories but containing a
blend of carbohydrates, these foods also help to keep overeating in check by causing
your cat to feel full faster.
Another perk of foods formulated for house cats is that such products often contain
fiber. As it does for humans, fiber helps to maintain proper digestion, and in cats, it can
also aid in the prevention of hairballs. If your cat is a longhaired breed or already suffers
from hairballs, you may additionally wish to provide fresh grass -- available at most pet
stores. “Cats in nature chew on grass to help pass hairballs,” says Mark Hanks, DVM, at
Kindred Spirits Veterinary Clinic in Orrington, Maine. “The long stem fiber of grasses
intertwines with the hair to help move it through the GI tract. I especially like oat grass
for managing hairballs because it is particularly high in antioxidants that benefit the cat.”
In addition to feeding your cat the right foods, here are some dos and don’ts for keeping
your indoor cat fit and healthy:
Do play with your cat every day. Also provide toys and catnip for your kitty.
Don’t give your cat human food, except as a rare treat, since it can lead to weight gain.
“Giving a cat human food is comparable to a human eating three doughnuts in addition to
a regular daily diet,” says Dr. Braun.
Do give your cat a scratching post and climbing structure to encourage activity.
Don’t buy food with only cost in mind. Go for the highest-quality food you can afford
that best matches the particular health and life stage needs of your cat.
Don’t give milk to your cat. Many felines cannot digest it properly and could get diarrhea.
But do provide a fresh, clean bowl of water at all times.
Do get your cat a friend, if possible. “Cats living in a household with a dog or other cats
are less likely to be obese,” says Dr. Hohenhaus.
The health risks for indoor cats are far fewer and much less serious than for cats that live
outside. The risks are also avoidable. By feeding your indoor kitty the right foods and by
encouraging activity, you can help to sidestep health problems that can cause expense
and heartache down the line. “An ounce of prevention is worth a pound of cure,”
concludes Dr. Hohenhaus.
