Hairballs in Cats
There's nothing quite like the glorious feeling of stepping out of your warm bed onto a cold, squishy, slimy hairball!
Perhaps we should feel flattered that our beloved feline companion has left a piece of herself as a special gift for us,
but frankly, most of us would rather bond with our cats another way!
What causes hairballs in cats?
Nature gave cats lots of wonderful, soft fur. Normally, when kitty grooms and ingests the dead, loose hair, it passes
through the gastrointestinal (digestive) tract and comes out in the stool. A carnivore's gut is designed to handle fur,
its own as well as the fur attached to prey animals. (If you've ever been hiking and come across "scat" from a coyote
or fox, it's evident that it is mostly fur.) However, generations of directed breeding have created cats with much
longer coats than ever conceived of by natural selection. And some cats, even shorthairs, just seem to have tender
tummies. When too much hair collects in the stomach rather than passing out through the gut, it irritates the
stomach lining and whoops — there's a hairball, on its way back out the wrong end of the cat! (By the way, the
correct medical term for a hairball is "trichobezoar," pronounced trike-oh-bee-zohr — your vet will be impressed!).
Problem signs of Hairballs
While an occasional hairball is no cause for alarm, if your cat is vomiting up a hairball more than once or twice a
month, it's time to think about a plan of action. This will probably start with a trip to your veterinarian for a
thorough exam. It's important to make sure the problem is only hairballs and not something more serious. Problem
signs include hearing the "Hairball Hack" — that awful coughing sound cats make when trying to expel an
offending ball of fur — if no hairball is forthcoming; and any frequent vomiting. Coughing without expelling a
hairball can signal feline asthma, and frequent or persistent vomiting of any kind should always be checked by your
A Holistic view
From a holistic point of view, excessive trouble with hairballs indicates a basic systemic or energetic imbalance. A
holistic veterinarian would consider the entire cat, including history, previous medical problems, diet, environment,
social and family issues — even the cat's personality. Hairballs would be just one symptom, one that will be weighed
in totality with all the other information. For instance, a cat that follows the sunbeam all over the house, and sleeps
next to the heater vent would receive different treatment than a cat that sits next to an open window in the dead of
winter, even if they both displayed the "symptom" of frequent hairballs.
Prevention of Hairballs in cats
Prevention, as they say, is worth a pound of cure. Frequent combing is often all it takes to resolve the problem. But
brushing won't do. Brushes tend to slide over the surface of the fur and don't get all the dead hair out. For
shorthaired cats, a fine-toothed flea comb is best. Longer hair may require a wide-toothed comb, or one with
revolving teeth to prevent tearing out the hair.
Many hairball-plagued cats will try to self-medicate by eating grass or plants. The coarse plant fibers will cause the
cat to vomit, and hopefully, the irritating hair will come up as well. Not all grass-loving cats have hairballs, however.
You need to carefully observe your cat so you can accurately report the situation to your veterinarian.
Treatment for hairballs in cats
Hairball treatments generally fall into two categories: adding fibre to the diet, or giving a lubricant (usually a
petroleum jelly product) to slide the hair through to the correct end of the cat for disposal. A third option, which
might be used by a holistic vet, is homeopathy. A good remedy for foreign material in the stomach is Nux Vomica. A
dose of Nux will often help the cat expel all the problematic material — but then you have to deal with a big fat
hairball on the floor. In practice, I used Nux to oust some major league hairballs, as well as the occasional chicken
bone or baby sock.
For many years, the treatment of choice for hairballs has been petroleum jelly. This can be given plain, as in good
old Vaseline, or in a commercial product, such as Laxatone, Petromalt, or Katalax. These come in malt, tuna, and
liver flavors that appeal to many cats. Petroleum jelly's molecules are too large to be absorbed by the intestines; it
passes through the cat unchanged, and is perfectly safe. I fed my cat, Spirit, plain Vaseline every day her whole life
— she lived to be well over 20, so I feel confident in saying it didn't hurt her at all. In fact, she loved it, and would
pester me mercilessly for her bedtime dose! Administer daily for a week or two, then once or twice a week for
maintenance. Hairball "treats" contain mineral oil rather than petroleum jelly. It works on the same principle, but
has a slightly more laxative effect — don't overdo them! Edible oils, like olive, flaxseed, or fish oil, will be absorbed
by the intestines and thus may not finish their escort duty, although a cat with dull or dry fur would benefit from
the fatty acids they contain.
If your cat is not a petroleum jelly connoisseur, the traditional method of administering it is to smear a glob of it on
a front paw. But be careful! A chunk of goop on a paw is liable to be flipped off in one quick and very efficient
motion. My first apartment probably still has Vaseline on the ceiling! It's better to spread it on the leg below the
elbow, or any place it's easy for your cat to lick off. You can also put a dab into a syringe and force-feed it to your
cat, but if it comes to this, you're probably better off with a more kitty-friendly method of treatment.
Diet for hairballs
Fibre is relatively easy to add to the diet. There are a lot of hairball control cat foods and treats out there. How do
they work? The general idea is that the higher fiber content will help hair pass through the gastrointestinal tract,
out the other end, and into the kitty litter box where it belongs. Many hairball diet foods contain powdered
cellulose and other fibers like beet pulp, while hairball treats can contain mineral oi
l, a laxative that works much like petroleum jelly products in helping "slide" undigested hair through the intestines.
The "natural vegetable fibre" is commonly powdered cellulose. Fibre is thought to bind the hair and stimulate the
gut to help move it on through the digestive tract. You can also use canned pumpkin (up to 1 tbsp. twice a day,
plain or mixed with wet food). Some cats like the taste, most don't seem to mind it, and a few won't have anything
to do with it. Psyllium or rice bran may also be added to food. Don't overdo the fibre, though: too big a dose at one
time will "roto-rooter" the gut and cause diarrhea. Most hairball diets on the market have 2-10 times the normal
amount of fiber, which is potentially irritating to the tender lining of the gastrointestinal tract. If you try one of
these foods, make the switch gradually, and be sure to watch closely for too-loose or too-dry stools; either may
However, high fibre may have some serious drawbacks down the road. Besides a potential for
diarrhea/constipation, there are a number of other possible concerns:
Excessive fibre holds water in the gastrointestinal tract, which results in a more concentrated urine, which could
increase the risk for urinary tract disease. Cats should be thirstier and drink more water on a higher fibre diet, but
that doesn't mean they will.
More fibre causes more stool and increased bulk, which may be undesirable to some people. No more hairy messes
on the carpet, but a lot more stools in the litter box!
Even if the fibre increases intestinal mobility, it may not force the hair to pass out of the stomach, which is the real
problem with hairballs — they get stuck in the stomach, not the intestines. No one has proven that fibre does
anything to enhance stomach contractions or gastric emptying. Petroleum jelly products, on the other hand, do
appear to get the hair out of the stomach.
Since there can never be more than 100% of ingredients, an increase in fibre means a decrease in something else.
And the ingredient lists of many hairball formulas are suspiciously similar to light/diet foods. Some light/diet foods
have even more fibre than the hairball formulas (but less fat).
Bloating, cramping or gas may occur as fibre is increased in the diet. For kitties, this can usually be minimized with
a gradual switch of foods, but is something to keep in mind if the cat seems uncomfortable.
The hairball formula can be more expensive than maintenance diets of the same brand, even though fibre is a very
On the positive side, many hairball formulas promise improved coat condition and a decrease in excessive hair
shedding. But so do a lot of maintenance diets. Most of the hairball foods' packaging recommends regular
grooming sessions in combination with their food to keep hairballs down (or move them on through) — which is one
of the best ways to decrease hairballs anyway, you don't need a special diet to accomplish that!
Many cat lovers who prepare homemade diets for their feline companions say that hairballs are much less of a
problem. The cat actually has little, if any, physiological need for fiber, and it does make sense to feed what nature
intended the cat to eat: meat, fat, a few organs, a little bit of vegetable matter — and, of course, hair!
So don't despair; with just a little effort, soon it will once again be safe to get out of bed!
