Mats are clumps of shed undercoat that tangle with live hair until they form tight knots against the skin. They pull every time the cat moves, can hide sores and parasites, and can trap moisture in a humid climate. Small, loose tangles can often be teased apart with a comb and patience. Mats that are tight to the skin should be clipped out by a trained groomer or veterinarian, never cut with scissors at home, because cat skin tents up into the mat and is easily sliced.
Why cats get matted
Every cat sheds. Short-haired cats usually remove loose fur themselves with their rough tongues. Long-haired and semi-long-haired cats often cannot keep up, and the shed undercoat stays trapped among the guard hairs. Movement, friction and moisture then twist it into knots.
- Coat type: Persians, Himalayans, Maine Coons, Ragdolls and many long-haired mixed breeds are especially prone.
- Friction areas: armpits, behind the ears, the belly, the inner thighs, under the collar and around the rear.
- Weight and age: overweight and senior cats often cannot reach their backs and hindquarters. Arthritis makes twisting to groom painful.
- Illness: a cat that suddenly stops grooming may be sick, in pain or have dental problems. A fast decline in coat condition is a reason to see a veterinarian.
- Humidity: damp fur clumps more readily, and in South Florida the air stays humid for much of the year.
Why mats are more than a cosmetic problem
| Problem | What happens |
|---|---|
| Pain | Tight mats pull the skin with every movement. Cats may stop jumping, avoid being touched or hide. |
| Skin damage | Moisture and heat build up under the mat, which can lead to redness, sores and infection. |
| Hidden parasites | Fleas and flea dirt are harder to see and treat under dense mats. See the guide to fleas and ticks in Florida. |
| Hygiene | Mats near the rear can trap feces and urine, attracting flies and causing irritation. |
| Pelting | In severe cases the whole coat knits into a single sheet that restricts movement and must be shaved off. |
What you can safely do at home
Small, loose tangles
- Choose a calm moment, ideally when the cat is relaxed or sleepy.
- Hold the hair at the base of the tangle, between the mat and the skin, so pulling does not reach the skin.
- Use the end teeth of a wide-toothed steel comb to pick at the outer edge of the tangle, working inward a few hairs at a time.
- Stop after a few minutes or at the first sign of tail twitching or flattened ears. Come back later.
- Reward the cat with a treat after each short session.
A small amount of cornstarch worked into a tangle can help some owners loosen it. Avoid human hair products and anything containing essential oils, which can be harmful to cats.
What not to do
- Do not use scissors on a mat close to the skin. The skin is pulled up into the mat and is very easy to cut. This is a common reason cats need stitches after a home grooming attempt.
- Do not bathe a matted cat before the mats are removed. Water tightens mats and makes them harder to clip.
- Do not force it. A cat that learns that grooming means pain will fight every future session.
Professional mat removal
A groomer will usually assess how close the mats are to the skin. Loose mats may be brushed or split. Tight mats are clipped out with a blade that slides between the mat and the skin. When there are many mats, the kindest and fastest solution is often a short clip of the affected areas or a full body clip, such as the lion cut. Many groomers follow a "humanity over vanity" approach, meaning they will not spend hours dematting a cat in pain just to preserve length.
Cats with severe pelting, open sores under the mats or a history of biting may be referred to a veterinarian, who can examine the skin and, if appropriate, groom the cat under sedation. The page on grooming anxious or aggressive cats describes that process.
Preventing mats
| Coat type | Suggested combing routine | Tools |
|---|---|---|
| Short coat | Weekly, more often during heavy shedding | Rubber curry brush or fine comb |
| Medium coat | Two or three times a week | Slicker brush plus steel comb |
| Long coat | Daily or every other day, focusing on friction areas | Wide- and fine-toothed steel combs, slicker brush |
Finish every session with a steel comb that reaches all the way to the skin. If the comb glides through, the coat is clear. If it catches, there is a tangle forming. Keeping sessions short and pleasant matters more than doing everything at once. Regular professional grooming every few weeks can also stop mats from building up; see the comparison of grooming settings to decide where.
Frequently Asked Questions
Can I cut mats out of my cat's fur with scissors?
It is not recommended. Cat skin is thin and gets pulled up into the mat, so it is very easy to cut. Small loose tangles can be combed out; tight mats should be clipped by a groomer or veterinarian.
Why is my cat suddenly getting mats?
Weight gain, arthritis, dental pain and illness can all stop a cat from grooming. A sudden change in coat condition is a reason to book a veterinary check rather than only a groom.
Does shaving a matted cat hurt?
Clipping itself should not hurt when done carefully, and it usually ends the constant pulling the mats cause. The skin underneath may be red or sensitive afterward, especially if the mats were tight for a long time.
How can I tell if a mat is too tight to brush out?
Try to slide a comb between the mat and the skin. If you cannot get under it, if the mat feels like a solid lump, or if the cat reacts in pain when you touch it, leave it for a professional.
Will a bath help loosen mats?
No. Water usually makes mats tighter and harder to remove. Mats should be removed before any bath.
