Mats are what happens when loose undercoat tangles into the top coat and felts together — and once a mat forms, it only gets tighter. It pulls on the skin every time your cat moves, traps moisture and grime underneath, and can hide sores you can't see. Here's how to deal with mats safely, and how to know when it's a job for a professional.
First, the one thing you must never do
Never cut a mat out with scissors. A mat pulls the skin up into itself, so what looks like a safe snip through fur is very often a cut into skin — cat skin is thin, stretchy and tears badly, and scissor injuries from home dematting are one of the most common reasons cats end up at the vet after "grooming". However careful you are, you cannot see where the mat ends and the skin begins. Put the scissors down; everything below is safer.
Why cats mat
Healthy cats do most of their own coat care, so matting is usually a sign something has changed:
- Age. Stiff, arthritic cats physically can't twist to groom their back and hindquarters — which is exactly where senior cats mat first.
- Weight. Overweight cats can't reach, same result.
- Coat type. Long, soft, dense coats (see the breed notes below) mat faster than the cat can maintain them, even in perfect health.
- Season and grease. Spring moult multiplies loose undercoat; an unneutered or unwell cat's greasier coat clumps sooner.
- Illness. A cat that has stopped grooming itself altogether often doesn't feel well — sudden widespread matting in a previously tidy cat is worth a vet conversation, not just a groomer one.
Small mats: what you can do at home
If the mat is small (fingertip-sized), loose, and your cat tolerates handling:
- Work it with your fingers first. Hold the base of the mat against the skin with one hand — so you're pulling on the mat, never the skin — and gently tease it apart from the ends inward. A pinch of cornflour or unscented talc-free grooming powder helps the fibres slide.
- Then comb, don't brush. A wide-toothed metal comb or a dematting comb, short strokes at the outer edge of the mat, working slowly toward the base. A slicker brush glides over the top of a mat and tells you nothing.
- Keep sessions short. Five minutes, treats, stop before the cat's patience runs out. Three short sessions beat one battle.
- Never bathe a matted cat. Water shrinks and tightens mats into felt. Dematting always comes before any bath.
If the mat is tight to the skin, bigger than a couple of centimetres, in a painful spot (armpits, groin, behind the ears), or your cat won't have it touched — stop. That's the line.
When it's a professional job
A groomer with proper cat experience has clippers, not scissors, and the technique to use them on thin feline skin. For widespread matting the kind option is usually a shave-down (lion cut) rather than hours of tugging — fur grows back; trust in being handled is harder to regrow. Expect £45–75 depending on severity, and see our lion cut guide for what that involves.
For cats who are truly pelted — a solid felt layer you can't lift — or cats who become aggressive when handled, the right venue is a vet practice, where the coat can be removed under sedation. It's more expensive, but it's painless and safe, and any skin damage hiding under the pelt gets treated on the spot.
Breed notes: the usual suspects
- Persians have the highest-maintenance coat in the cat world: long, soft and woolly with a fine undercoat that felts if neglected for even a week or two. Daily combing is genuinely necessary, and most Persians do best with a professional groom every 6–8 weeks regardless.
- Maine Coons carry a heavy, semi-water-resistant coat that mats in the classic friction spots — armpits, britches, belly and the famous trousers. Two or three thorough combs a week keeps most Maine Coons mat-free.
- Ragdolls have a silky semi-long coat with less undercoat than a Persian, so they mat slower — but the soft texture means that when mats do form (collar area, behind the ears, hindquarters) they tighten quickly.
- British Longhairs combine a plush dense undercoat with a laid-back temperament that hides discomfort; check them by touch, not just by eye.
Prevention: five minutes that saves a shave
A metal comb to the skin — not a bristle brush over the top — a few times a week is the whole trick. Work the friction zones: behind the ears, under the collar, armpits, belly, trousers. Start the habit young if you can, keep sessions short and pleasant, and pair with treats. For long-haired breeds, add a standing appointment with a cat groomer every 6–8 weeks; maintenance grooms are cheaper, quicker and far kinder than rescue grooms.
