Cats are fastidious and groom themselves frequently with their tongues, so they can inadvertently swallow a lot of hair. The result for some cats is horrendous hairball hassles.
It’s not only a problem for long-haired kitties. Because a cat’s hairs are replaced roughly every thirty days, even short-haired cats can ingest a lot.
Usually this hair passes through the gastrointestinal tract unnoticed, but sometimes it gathers into sticky balls that your cat has to cough up. Otherwise the hairballs will block up the cat’s digestive tract and cause constipation.
The best way to avoid hairballs is to brush your cat frequently. If this doesn’t solve the problem, ask your veterinarian for a special laxative.
