Hairballs are the butt of many a cat joke, even though the telltale hack-hack-hacking may seem commonplace to most feline owners. Cats are fastidious self-groomers, so it’s this habit that causes hairballs -- swallowed loose fur that is not completely digested. The problem usually warrants no cause for alarm, but in some cases, hairballs become too big for a cat’s digestive tract and cause blockage that can be life-threatening. It’s important for any cat owner to know why hairballs form, why they’re so common and when they can be dangerous.
“Most cats will either vomit the hair or pass it in their stool,” explains Tami Groger, DVM, associate veterinarian at Bay Hill Cat Hospital in Orlando, Fla. The feline digestive system is designed to handle hairballs (called trichobezoars by doctors) but only up to a certain size. “We had a long-haired kitty who stopped eating for three days and just did not look comfortable,” recalls Bernadine Cruz, DVM, of Laguna Hills Animal Hospital in California. “Everything seemed normal, but when I [felt] her abdomen, there was something there under the rib cage. We took an X-ray and saw this big thing. We did surgery to remove one huge hairball -- at a cost of $2000.”
The kitty recovered fully, but the owner may still be recovering from that bill.
Another problem caused by hairballs is that sometimes their symptoms appear similar to respiratory problems, such as asthma, which also require a veterinarian’s attention. Keeping hairballs to a minimum will therefore help your veterinarian diagnose asthma more quickly, should your cat develop it.
All cats get hairballs, says Dr. Groger, but “they are more prevalent in the long-haired breeds -- Persians, Himalayans, Maine Coons and domestic long hairs.” She adds, however, that she has “seen problems with short-haired cats, as well.”
Hazardous Hairball Warning Signs
Three key symptoms can distinguish a not-so-worrisome hairball from one that may require immediate medical attention. These are:
All three of these symptoms could mean that your cat’s throat, stomach or intestines are blocked by a hairball obstruction. If your cat exhibits any of these symptoms, schedule a visit to your veterinarian’s office as soon as possible.
How to Prevent Hairballs
The best defense against hairballs, dangerous or not, is to keep your cat from getting them in the first place or to make sure they can be digested. Here are some tips recommended by veterinarians.
Hairballs are an unpleasant side effect of your kitty’s natural inclination to stay clean and beautiful. Our job as cat owners is to allow that self-grooming but take responsible steps to make sure it doesn’t result in a dangerous, albeit hairy, health hazard.
