How to Deal with Hairballs in Cats

1 Why Hairballs Are Dangerous

Cats are fastidious and groom constantly with their barbed tongues, swallowing some hair each time. In the stomach this forms a ball. If it is not passed, it builds up and easily brings on poor appetite, nausea, dry retching, and constipation — and in serious cases, full hairball syndrome.

A common myth is that a cat will vomit the ball up on its own. In reality the mass hardens and grows in the digestive tract and, at its worst, can cause an intestinal blockage that only surgery can clear. That is why hairball paste and cat grass should be given regularly to help clear the small balls early.

2 When to Start Hairball Paste

Very young kittens do not need paste — the mother cat grooms them, so they swallow little fur and rarely vomit balls. From 3–4 months a kitten grooms itself more often, and after 4 months it enters a natural shedding phase with lots of loose fur, so a little paste can begin then. If yours is a short-haired cat that sheds lightly, wait until 7–8 months to start.

3 Prevention

Cat grass stimulates gut movement so the cat can bring some hair up by vomiting. It also freshens the mouth and eases stress, so grow a patch at home — a cat that feels a ball forming will eat the grass on its own.

Hairball paste suits picky cats that refuse grass. It lubricates the intestine so the ball passes out with the stool, sparing the cat the distress of vomiting.

Brush daily. Removing loose fur before the cat swallows it slows ball formation, cuts the fur flying around the house, and improves circulation and skin immunity.

A hairball-control diet helps too. Some foods add a special formula that reduces fur buildup; check the product is safe and avoid relying on it long term.
