Despite constant grooming, hairballs still normal for cats

Cat parents know the sight and sound of their cats throwing up hairballs. Some may cry while others may not, but that retching sound is hard to miss before a clump of undigested hair is expelled.

Cats are consummate groomers. As they clean themselves, they loosen and swallow dead hair. Most of this hair moves through their digestive tracts and ends up in litter boxes. Hair that remains in their stomachs form into hairballs.

Cats must vomit to oust them. Hairballs often appear tubelike, formed as they pass through the esophagus. They can be small - just an inch long - or considerably longer.

Kittens are less likely to throw up hairballs than older cats who are better at and spend more time cleaning themselves. Long-haired breeds, like Maine Coons and Persians, experience more hairballs than short-haired cats. Hairballs are also more likely when cats are shedding seasonally.

It is not uncommon for cats to vomit up a hairball every few weeks or so, and normally it's nothing to be concerned about. If, however, they occur more frequently, or if cats have recurrent retching episodes without producing a hairball, it is time to call a veterinarian.

Other symptoms of hairballs causing a health concern for cats are loss of appetite, lethargy and constipation. Hairballs can move from the stomach into the intestine, forming a blockage. A veterinarian can confirm an intestinal blockage by doing an exam, performing blood tests and taking a radiograph. Treatment may include medications to encourage the hairball to continue on its way or surgery may be required.

To help your cat reduce the number of hairballs, brush him every day. Brushing removes some of the loose hair that might end up in his stomach.

Also, make sure your cat is engaged with his environment. A bored cat may be more likely to fill his time grooming. Keep him active - physically and mentally - with some new toys from time to time. Why not combine daily brushing with some daily playtime?

Consult with your veterinarian about products and remedies to prevent hairballs. There are a variety of shampoos, wipes and lubricants in the marketplace. Some may work; some may not. Your veterinarian will help you decide which products are appropriate for your kitty. Note that it is not advised to administer a lubricant without first visiting your veterinarian.

There are a number of cat food brands that offer foods formulated to reduce hairballs. These foods are high in fiber to help move hair efficiently through the digestive tract. Again, your veterinarian is your best resource for a recommendation.
