Longhaired cats need 10-15 minutes of combing every day during the 4-8 week shed in spring and autumn, and 2-3 sessions a week the rest of the year. The work is not cosmetic: a mat pulls on the skin constantly, stops the coat from insulating, and hides wounds and lumps. Most of what goes wrong is not a difficult coat but a comb that never reaches the skin.
The schedule by season
Shedding season, roughly March to May and September to November, means daily sessions of 10-15 minutes. A longhair in full coat can shed a handful of undercoat a day, and that loose hair felts into the base of the coat within 48-72 hours if it is not combed out.
Outside those weeks, 2-3 sessions a week is enough for most cats, plus a 2 minute check of the four mat zones: behind the ears, the armpits, the inner thighs, and under the tail. Senior cats, overweight cats, and cats with arthritis need daily work on the rear half, because they stop grooming the parts they cannot reach.
Tools that do the work
Three tools cover nearly everything, and one of them is not a brush. A slicker brush lifts loose hair from the surface; a stainless steel comb with two spacing widths checks whether you have actually reached the skin; a dematting comb with a small blade splits a mat that has not yet set. A wide-tooth comb handles the tail and the britches.
| Tool | Job | Notes |
|---|---|---|
| Slicker brush, fine or medium pins | Lifts loose undercoat | Never press hard; pins scratch skin |
| Stainless comb, coarse and fine ends | Tests the result | If it will not pass, the coat is not done |
| Dematting comb with blade | Splits grade 2 mats | Short strokes outward, never into skin |
| Wide-tooth comb | Tail, britches, behind ears | Start at the tip, work upward |
| Clipper with a 10 blade | Grade 3 mats, sanitary trim | Only tool for felted coat; scissors cause cuts |
The comb is what separates grooming from petting. Run it through a section; if it stops, there is a mat under the surface that the slicker just polished. Work in sections the width of the comb, from the tail forward, and comb in the direction the hair grows, then against it once to check.
Grading a mat: three levels
Grade 1: a tangle at the surface, airy, and a comb passes under it with a little tug. Comb it out from the tip in short strokes, holding the hair between the mat and the skin with two fingers so the pull does not reach the skin.
Grade 2: felted, close to the skin, and no comb entry at all. A dematting comb can split it into sections, but this is 10-20 minutes of work per mat and the cat will not tolerate many. If there are more than 3 or 4, shave the area.
Grade 3: a solid plate stuck to the skin, often with dandruff or a red patch underneath. Do not comb it, do not cut it with scissors, and do not pull. Shave with a clipper, or have a groomer or vet do it. Cat skin is 2-3 mm thick and tents up into a mat: scissors cut skin more often than they cut hair.
Never pull, and why
A set mat is attached to the skin across its whole base. Pulling it lifts the skin with it, and cat skin tears rather than stretches, which is how a 3 cm mat becomes a wound. The same reason rules out holding the cat down: a struggling cat tears its own skin against a comb.
If a mat has to come off and no clipper is available, cut it in half across the middle with rounded-tip scissors while a comb sits between the blade and the skin, then work each half outward. Stop at the first sign of resistance.
Order of work
Start at the rear, where mats form first and the cat is least tolerant, and finish at the head, which most cats enjoy. Hind legs and britches, then the belly line, then the flanks, then the chest and armpits, then behind the ears, then the tail in sections. Two short sessions beat one long one: a cat gives you about 10 minutes before the tail starts flicking, and after that you are wrestling.
The sanitary trim
Longhairs need the hair around the anus and the back of the thighs shortened to about 5 mm, or 1 cm around the vulva in females. This is not cosmetic: feces caught in the coat builds into a hard mass that pulls skin, blocks self-cleaning, and attracts flies in summer. A 10 blade clipper with the skin held flat does this in 2 minutes; a groomer will do it for a small fee if you are not confident.
Check the area daily in a cat with soft stool. A matted plug of feces needs to be softened with warm water and cut away, never pulled off.
Bathing and the drying rule
Most longhairs need a bath every 4-8 weeks, or when the coat feels greasy at the base of the tail. Use a cat shampoo at about 38 C water, work it into the undercoat rather than the surface, and rinse until the water runs clear, which often takes twice as long as the wash.
The coat must be dry to the skin before the cat is released. A damp undercoat stays wet for hours under the top layer, and warm damp fur is where Malassezia yeast and fungal skin infections start; mats also tighten as they dry, so a cat put away damp comes out felted. Budget 20-40 minutes with a forced-air dryer on the lowest heat, or a towel and a warm room, and check the armpits and groin by hand.
When to see a vet
Book a visit for a mat with a red, weeping, or foul-smelling patch underneath, a sudden coat change on one side, symmetrical hair loss on the flanks, or a cat that stops grooming its rear. Over-grooming that leaves bald patches on the belly or inner thighs is usually itch, pain, or stress, not a grooming failure. Ringworm in a longhair hides under the coat and shows as broken hairs and scale, not a neat round bald spot.
Five steps for this week
Buy a stainless comb and use it as the test, not the slicker. Book 10 minutes a day during shed season and check the four mat zones in between. Grade every mat before touching it and shave anything felted to the skin. Trim the sanitary area to 5 mm. If you bathe, plan 40 minutes of drying time before the cat leaves the bathroom.
Frequently asked
Can I just shave my longhaired cat for the summer?
It is sometimes the right call, but not as routine cooling. The coat insulates against heat as well as cold, and shaving removes that buffer and exposes 2-3 mm of skin to sun, which is how cats get actinic dermatitis on the ears and nose. Shave when mats are widespread, after Ringworm treatment, or on vet advice for a cat that cannot groom. A sanitary trim and a lion cut with the body left at 1 cm are safer than a full shave.
How do I stop mats coming back behind the ears?
Behind the ears is where the coat changes direction and where grooming stops, so it needs a deliberate pass every session rather than a casual stroke. Use a wide-tooth comb and lift the hair away from the ear leather instead of combing along it, and check with the fine end of a stainless comb. In a cat that scratches there, look for ear mites or a yeast infection, because scratching is what creates the mat in the first place.
My cat hates being brushed. Where do I start?
Start with 60 seconds in a place the cat already relaxes, usually a windowsill or the bed, and stop before the tail flicks rather than after. Brush one section only, then give a treat and leave. Build to 5 minutes across 2 weeks, and do the difficult rear half in a second short session rather than extending the first. A cat that fights for 10 minutes learns nothing except that the comb predicts a fight.
