Grooming, The Feline Purrspective

Canned food spread on a textured silicone mat can give your cat the enjoyment of licking without ingesting fur.

As you are en route to the bathroom during the night, your foot contacts something tubular and mushy – another hairball! I have lived with over a dozen cats – some I have shaved to reduce the hairball menace; others I have dutifully given the hairball gels, which promise to lubricate the cat’s GI (gastrointestinal) tract to help the hairball pass. But, are hairballs normal, part of something you have to put up with when owning a cat?

Hairballs are rare to non-existent in feral cats and zoo cats. Why do our domestic cats get hairballs? Hair that is ingested during normal grooming activities passes out the intestines in the stool. On average, a short‐haired cat loses about 28 g of hair per kg of body weight each year. Two‐thirds of this hair consumed while grooming is found in the stool (Reference 1). The more the cat grooms herself, the more hair she consumes. Couple this with slower gastric emptying, hair can accumulate in the stomach, forming a hairball. Here are the “why’s” and “how’s” of managing hairballs in cats.

managing hairballs in cats

If a hairball becomes too large to pass through the GI tract, the cat usually expels the hairball by vomiting. However, if vomiting is not successful, we risk (Reference 2)

intestinal obstruction
obstruction of the esophagus
hair lodging in the nasopharynx (top part of the throat throat just behind the nose) causing sneezing, retching, and nasal discharge

How Common Are Hairballs in Cats? (Reference 2)

73% of cats have never had a hairball
17% cats bring up a hairball once a year
10% bring up two or more hairballs in a year
Long-haired cats are twice as likely to vomit hairballs than short-haired cats

When Do We See (or Step on) Hairballs?

Flea infestations can lead to increased grooming
GI motility is decreased due to food intolerance or gastrointestinal disease
The cat is “over-grooming” due to anxiety

What to Do About Hairballs

Chronic gastrointestinal disease, pain, and/or stress can change how fast hair and food move through the GI tract. Your first stop should be your veterinarian’s office. Appropriate management of GI disease can significantly reduce hairball vomiting (Reference 2). Your vet will consider dietary therapy and run diagnostics to detect GI disease.

Diet and Hairballs

Diet may be helpful in managing hairballs in cats. Studies have found that diets containing moderate levels of fiber (11-15% total dietary fiber) can minimize hairball formation, particularly in long-haired cats. Fiber aids in increasing the amount of hair passed out in the stool (Reference 1).

Hairball diets also have larger sized kibbles. Radiographic studies have linked larger kibbles with hairballs exiting the stomach and passing out in the feces (References 1, 2).

Consider feeding more canned food. Canned food passes through the GI tract more quickly (about 4 hours) compared to dry kibble (14-16 hours) (Reference 2).

The following strategies may help reduce the amount of hair ingested and promote GI motility (Reference 2).

daily grooming to reduce loose hair
shaving long-haired cats
monthly flea prevention
increase gastric emptying by feeding frequent small meals rather than large meals
use petroleum-based laxatives to lubricate the intestinal tract easing the passage of hairballs
prokinetic drugs (metoclopramide, cisapride, ranitidine) promote GI motility

hairballs in cats: environmental modification

The GI tract is very responsive to psychological stress. Stress, chronic GI disease, and pain are factors that can affect how fast ingesta are processed by the GI system (Reference 3).

Domestic cats spend 25-30% of their waking hours grooming; those kept solely indoors may spend even more time at this task. Grooming may increase when the cat is stressed or bored.

Enironmental modification gives us a way to reallocate the cat’s time budget – giving him/her other activities to do, in addition to grooming. It also helps us reduce the stress perceived by the cat. In addition to providing the requirements for a healthy feline environment, the following strategies can affect the feline time budget.

feeding frequent small meals (may also help with gastric emptying)
incorporating species specific behaviors in feeding strategies (Why Meal Feed Your Cat)
providing outdoor access in an enclosure or on a harness and leash
regular interactive play time
establish a routine; allow the cat control over his environment by knowing what will happen and when

Grooming is a self-soothing behavior. The use of lick mats (textured silicone mats that you spread food on) can take advantage of the satisfaction cats find in licking without hair ingestion.

Although hairballs may seem to be a nuisance behavior, frequent vomiting of hair balls is NOT normal and can be an indicator of underlying GI disease or stress. A visit to your vet can diagnose medical problems; implementing environmental modification can reduce stress that affects how much cats groom and how fast hair moves through the GI tract.

A cat’s first experience with grooming is when she is born. In the first 3 weeks of life, her mother cleaned her nose to tail many times a day, stimulating the kitten to void her bowels and urinate. When the kitten reached 4 weeks old, she started grooming herself, and also grooming her litter mates and mother.

why do cats groom?

Cats are mammals. Mammals have fur to maintain their high body temperature. The fur traps air next to the mammal’s body, providing an isolating layer to regulate his temperature.

It is important to keep the fur coat clean, after all a matted or pelted coat cannot trap as much air as a clean coat, where air surrounds each individual hair. Oil from the skin can combine with shed fur and dirt to form mats. Grooming helps distribute the oils of the skin throughout the fur so that mats are not likely to form.

Grooming not only helps keep your cat warm when cold and cool through the evaporation of saliva when hot, it also has a social function. A cat will not only groom himself, he also may participate in allogrooming. Allogrooming refers to animals of the same species grooming each other.

Grooming Your Cat – allogrooming

Some studies show that allogrooming occurs most among cats that are related, that are of the same social group. It is an affiliative behavior.

But there is also evidence that allogrooming is not restricted to family groups. It also a way for cats to redirect potential aggression and avoid physical conflict. Cats, being solitary hunters, prefer to avoid fighting. Fighting can result in injury, making a cat unable to hunt and feed himself.

In urban cat colonies and in multi-cat households, the abundance of resources make it possible for many cats to live close to each other, with abbreviated, overlapping territories. More cats closer together increases the likelihood of aggressive encounters. Allogrooming gives cats a way to redirect the aggression with a few quick licks to the head, soothing a would-be combatant and avoiding a fight.

I have two male cats, Gus and Marley, who are not fond of each other but co-exist. I was surprised the other day to find Gus grooming Marley’s head. Had Marley appeared aggressive to Gus? Marley is bigger than Gus – was Gus trying to calm Marley down to avoid a fight?

Grooming your cat: a social interaction

Cats often groom their people, licking them with their barbed tongues. How can we reciprocate? Consider grooming your cat. Grooming your cat can be soothing, making her feel calm and secure. And, it can help reduce hairballs and mats, by removing excess hair and distributing oils over the cat’s coat.

tips for grooming your cat

Make sessions short.
Note the rounded tines on this “greyhound” comb. There is a “coarse” and “fine” side.
Only groom part of your cat’s coat at a time – say, one side.
Consider using a comb with rounded tines – it is often more effective than a brush.
Comb at an angle, in the direction of the hair.
Don’t pull knotted or matted hair out – this hurts! Tease mats apart gently with your fingers if possible, then comb the area, starting with a “coarse” comb and working up to a “fine” comb.
Groom frequently, say every few days.

My cat won’t let me groom her

Treat Holder — Soft food, spread on the Lickimat, can be eaten by the cat during grooming.

Desensitize your cat to being groomed. Try distracting her with tasty treats – a “Likimat” can keep her engaged with a soothing behavior (licking) while you groom.

If your cat is clicker trained, try the following steps:

Establish a cue for grooming, for example, show your cat the grooming comb and let her rub against it.
Touch your cat with the comb, click and treat. Work up to brief combings – make sure to reward.
Gradually increase the time of combings, making sure to reward kitty.
WATCH her body language to know when to take a break.

Oil, dirt and shed hair can clump together to form larger mats that feel like Brillo pads. These mats are best taken care of by a professional groomer. Cats’ skin is delicate and can tear easily, requiring a trip to the vet for wound repair. Above all, resist the temptation to use scissors. Even small mats are best removed by hand or with a clipper.
