Why Some Cats Suck on Fabric, Wool, or Hair

Many cats develop a habit of chewing on wool, fabric, or hair (or, less commonly, other materials such as cardboard or plastic). This self-comforting obsessive-compulsive behaviour is similar to thumb-sucking in human children.

Chewing or sucking fabric or wool is particularly common in cats that were weaned too early. Early weaning may also cause cats to suck on an owner’s earlobes or fingers, or attempt to suckle on other pets. Cats should never be taken from their mothers before 8 weeks of age, and ideally should stay with them for at least 12.

Wool or fabric sucking may also be triggered by stressful life events such as the death of a loved one, harassment by another pet, or moving house. In many cases, the behaviour diminishes as the cat grows older, though some cats retain it throughout their lives.

Certain breeds such as the Siamese and Burmese are more inclined to develop the habit, indicating a genetic influence as well. These breeds need to nurse for longer, and so are more likely develop neurotic habits with early weaning.

How to stop cats from sucking on wool or fabric

The chewing habit is usually harmless unless the cat is actually swallowing pieces of fabric or knitted items (balls of wool should never be given to cats, as the wool can get caught on the barbs of their tongues, forcing them to swallow over and over again). Many owners tolerate the behaviour if items aren’t actually being ruined.

If you want to stop a cat from sucking or chewing on wool or fabric and it’s not convenient to keep targeted objects out of reach, there are safe spray-on cat deterrents such as Grannick’s Bitter Apple® and Veterinarian’s Best® Bitter Cherry Spray. If the behaviour is triggered by a stressful life event, providing additional reassurance and attention can be beneficial. Giving the cat something similar to the targeted item that he’s allowed to chew can also help.

Don’t give the cat any attention, positive or negative, when he chews or suckles on inappropriate items, as this will reinforce the behaviour. Making a fuss or punishing the cat is unlikely to reduce the behaviour and may actually increase it.

How to stop cats from chewing on hair

If your hair is the target, putting it up under a cap can help to break the habit.

Some cases of hair chewing are caused by a love of hair products (many of which contain oils or other fats that taste delicious to pets) rather than stress or early weaning. If your cat is attracted to your hair products because he likes their flavour, switching to a less tasty conditioner or gel should solve the problem.

If your cat is interested in hair only when you have been in a pool recently, it’s the chlorine that’s attracting his attention (chlorine smells like feline pheromones to some cats). Washing your hair directly after swimming will prevent hair chewing by chlorine-loving cats.
