Why Do Cats Get Hairballs?
The first time you see your cat hurl a hairball, you might be pretty worried. He'll retch and hack and try to bring it up. Then it will be there – on your rug or some other conspicuous spot – in all its undigested glory. Groom your cat. The more hair you can get off your cat by brushing, the less he will swallow. Brush your cat regularly with a brush, and then wipe your kitty down with a damp cloth to remove hairs missed by the brush.
Your cat may look distressed during all of this, but it's really nothing serious. A hairball, or trichobezoar, is just what the name says it is: a wad of undigested wet hair within the digestive tract. Generally, trichobezoars are not ball-shaped; they are sausage-shaped and are formed when the cat swallows too much hair after grooming.
As the cat licks his fur, dead hair comes loose. Because the cat's tongue has a rough surface made up of backward-slanting papillae, most of the hair cannot be dislodged, and the cat cannot spit it out. So he swallows it. Most of the hair goes through the digestive tract with no problem and is excreted in the feces; however, sometimes too much hair is ingested and the wad can't pass through properly. Instead, it accumulates in the stomach and forms a wadded mass.
Most cats suffer from occasional hairballs, some more than others. Long-haired cats tend to swallow more hair simply because they have more of it, but shorthair breeds get hairballs, too.
If the hairball is not regurgitated, it may create a blockage in the stomach or small intestine. If not treated, intestinal blockages create serious and even life-threatening problems for the cat. In severe cases, surgery may be necessary to remove the blockage. If you suspect your cat is having trouble passing a hairball, you need to consult your local veterinarian, especially if retching continues for more than a day, if your cat is constipated, or starts refusing its food.
What Can You Do?
Ask a cat owner what he would prefer: a cure for the common cold or a cure for hairballs, and the answer would likely be a cure for hairballs. But there is no cure. However, there are some things that you can do to minimize the rate of regurgitation:
Hairball products. If the problem still exists, you can also use petroleum-based products (such as Laxatone) that act as a laxative and lubricant to facilitate the passage of hair matted hair through the intestine. These products, which are pleasant tasting to cats, can be fed in paste form or applied to your cat's paws to allow your pet to lick it off.
Hairball remedy treats or food. You can also give your cat treats containing mineral oil, such as Pounce® hairball treatment, to break up the hairballs. Some pet food companies now manufacture food for cats with recurrent hair or fur ball problems. Ask your veterinarian what she or he recommends.
