“He’s throws up hairballs all the time,” is a common cat owner comment. To the pet owner the problem is simple. But to the veterinarian, it’s much more complicated.

When cats groom themselves That hair should then be swallowed. In a “healthy” cat, that

hair will go through the stomach and intestines (gastrointestinal tract) and come out in the feces.

So if a cat is throwing up hairballs, there is more going on than most owners realize.

Grooming allows cats to keep themselves clean. They remove old hair, surface dirt, and foreign bodies when they groom themselves and other cats.

But if a cat is long-haired, he/she has more hair to remove. So, long-haired cats who have to do all the grooming themselves — who aren’t being brushed by their owners — are ingesting more hair than the body can handle. The elimination of the extra hair may be too much for a healthy long-haired cat’s digestive system.

Also, if grooming becomes over-grooming, then more hair is entering the digestive tract, whether the cat is a short-haired or a long-haired cat.

Over-grooming can occur when a cat is stressed. Anxiety, emotional stress, etc., can cause a cat to groom himself more often and for longer times. It’s a coping mechanism, like the same way many children suck their thumbs to seek solace.

Over-grooming can also occur in cats experiencing pain. They may lick and groom the painful area to try to make it “feel better” and/or to reduce the stress. Urinary tract pain, musculoskeletal pain, and abdominal pain may cause over-grooming by the unhappy cat.

But hairballs also occur in animals who aren’t “putting too much hair” into their digestive tracts.

If the stomach and small intestine aren’t allowing the ingested hair to move through normally, then the cat will produce hairballs.

If the cat has inflammatory bowel disease, hair – and food – won’t pass through it at a normal speed, or at all. The stomach and intestinal tissue is damaged, and doesn’t provide normal motility. It also doesn’t produce the normal digestive enzymes or lubricants that allow the intestinal contents to move along.

The same is true of gastrointestinal cancer. The contents of the tract (hair and food) don’t move along the way it should.

So what does the veterinarian need to consider as potential causes of the hairballs? Intestinal motility problems, stress, stereotypic behaviors, skin disease, abdominal problems, urinary tract problems, and musculoskeletal problems.

To further define the scope of the investigation, what will the veterinarian have to rule in and out? Megaesophagus, diaphragmatic hernia, gastrointestinal neoplasia, ileus, intestinal parasites, inflammatory bowel disease, pancreatitis, gallbladder disease, cystitis, bladder stones, kidney stones, arthritis, boredom, frustration, skin parasites, fungal skin diseases, and more.

Not quite as simple as the problem the client discussed.

What diagnostic tests might the veterinarian need to perform? Complete blood count, blood chemical analysis, fecal examination, urinalysis, ultrasonography, radiography, contrast radiography, skin cytology, histopathology, behavior evaluation, etc.

Finding and treating the primary problem is always preferable to just treating the symptom (hairballs). The cat and the client will be happier if everything can be put back to normal. In addition to treating the inciting problem, though, the veterinarian may recommend diet changes, more brushing by the owner, more play time with the owner, etc.

With diagnostic skill and a little luck, the veterinarian can make the owner happier and the cat healthier and more content.
