Selkirk Rex Grooming: The Curl Is Hiding a Double Coat

Run your hand down a Selkirk Rex and it stops sooner than you expect. Not a tangle — there is just more coat there than the curls let on. The breed reads as a novelty: a cat with a perm, soft, rumpled, obviously low-effort. Underneath is a full double coat with a thick undercoat. The curl is the part you see. The undercoat is the part that matters.

What the Curl Is Actually Covering

The Cat Fanciers' Association describes the breed as the result of "a dominant, spontaneous mutation that causes each hair (guard, down and awn) to have a gentle curl giving the coat a soft feel." Every layer curls. That is worth sitting with, because it is the opposite of how the other curly breeds work — and it is why they get grouped together and shouldn't be.

A Devon Rex or a Cornish Rex is curly because it is missing hair. Most of the guard and awn layers are gone, and what's left is down, the fine stuff. A Selkirk Rex is curly because all three layers are there and all three are curled. The Australian Cat Federation standard, which takes its text from TICA's, is blunt about what that produces: "The coat is double with a thick undercoat and deep waves with curled ends." The guard hairs "tend to have a coarse texture, but the coat is very dense and overall soft and plush."

Dense. Double. Thick undercoat. Coarse guard hairs. Read that list with the word "rex" taken off the front and you would reach for a comb, not a towel.

The curl changes how much of that you can see, not how much is there. On a straight-coated cat, coat volume is visible — a Persian looks like a lot of hair because the hair is lying out at its full length. Coil the same quantity into clumps against the body and the cat looks like less coat than it has. Our breed-by-coat-type guide sorts cats by what the coat structure does rather than by what the breed is called, and this is a breed where those two answers disagree sharply.

Incidentally, the whiskers and eyebrows curl too, and come out broken-looking. That is a breed trait, not damage, and nothing needs doing about it.

Why the Curl Sits Exactly Where Mats Start

Here is the part that makes this more than a trivia distinction. Both registries say the curl is not evenly distributed. ACF: "The curl is most prominent around the neck, tail and belly." CFA puts it the same way — curliness is more evident around the neck, on the tail, and on the belly.

Those are the three places mats form on any coat with an undercoat. The ruff behind the ears and under the chin, the belly and the inside of the back legs, the base and underside of the tail. It is where the cat can't reach well, where friction happens, and where dead undercoat has nowhere to fall out to.

So on a Selkirk Rex the heaviest curl and the highest mat risk are the same real estate. The curl is not causing the mats; the undercoat is, the way it does in every double coat. But the curl is a very good lid. A compacting patch on the belly of a short-haired cat is something you notice. The same patch under a clump of curls is something you have to go find with your fingers.

CFA says, reassuringly, that "these cats do not mat easily" — and in the same breath gives the condition attached to it: "a good combing once or twice a month is recommended to remove dead hair and ensure that mats do not form." The claim and the maintenance are a package deal. For what happens when the second half gets skipped on a dense coat, the matting guide walks through how quickly a soft patch turns into a job that needs clippers.

The Breed Is Filed in the Wrong Drawer

Our breed grooming schedule groups cats by coat category, and the curly-coat rows — Devon Rex, Cornish Rex, LaPerm — share a theme: minimal brushing, watch the skin oil, the coat can't take mechanical stress. That advice is right for those breeds and wrong for this one.

The same page gives you the correct instruction for exactly this situation: match by coat, not ancestry, and if the cat has a dense double coat, follow that row. For a Selkirk Rex the row that fits is the British Shorthair one — plush, dense, double, an undercoat that blows out twice a year, professional grooming every eight to ten weeks. Not the rex rows.

The practical difference is seasonal. A double coat releases its undercoat in spring and again in fall, and a baseline routine doesn't keep up during those weeks. On a visible coat you find out because the house fills with hair. On a Selkirk you may get less warning, because a curled coat holds shed hair in place instead of dropping it. The back half of October is one of the two windows where that matters.

Set it next to the Devon Rex, where under-grooming genuinely is the right answer, and the contrast is clean. With a Devon Rex, less is more. With a Selkirk Rex, less is the trap.

A Flatter Back Isn't Neglect

One line in the ACF standard is worth more to owners than it is to judges: "The curliness of the coat on the saddle area of the back will vary due to climate and hormones especially in females."

That is a registry standard telling you the curl over the back is a moving target. Seasons change it. Hormones change it. So a Selkirk whose back has gone wavy, or nearly flat, while the neck and belly stay tightly curled has not been groomed wrong and does not need fixing. Chasing the curl back with a brush is how people flatten the rest of it.

Which is the one real argument against brushing here, and it isn't fragility. Selkirk hair isn't delicate — the standards call the guard hairs coarse. It is geometry. The curl is an arrangement, and a brush rearranges things. Run a slicker through a curled coat and the hair comes out fine; the pattern doesn't.

The Coat Takes Two Years to Finish

Here is something no grooming routine accounts for. ACF notes that kittens "may lack fully curly coat," that they "start to develop an adult curly coat at 8-10 months," and that "the coat will not reach full development until about 2 years."

Two years. The routine you settle into at six months is being applied to a coat that isn't finished, and the amount of undercoat you are managing at eighteen months is not what you were managing at eight. If you have had your Selkirk since kittenhood and your habits haven't changed since that first year, they are probably calibrated to a coat that no longer exists. Put a hand on the belly and the ruff and re-read it, rather than trusting the schedule you set.

Related, and worth saying because it blindsides people: straight-coated kittens do turn up in Selkirk litters, and they are registered as Selkirk Rex AOV. If yours never curled, nothing went wrong. It is still the same dense double coat underneath, so none of the grooming changes.

Selkirk Rex Grooming at Home

CFA's position on tools is refreshingly short: "No special grooming tools are needed to care for the Selkirk Rex coat." Read that as freedom from buying things, not as permission to do nothing.

• Comb once or twice a month, and get down to the skin. That is CFA's interval. The point isn't the surface — it is lifting dead undercoat out before it has a chance to compact. A comb parts the curl and passes through instead of re-styling the coat on the way.
• Finger-check the neck, belly, and tail base every week or two. Not a grooming session. A quick audit. You are feeling for a patch that is denser and less springy than the coat around it. That is an early mat, and at that stage a comb still fixes it.
• Fluff with your hands, not a brush. This is CFA's own instruction and it is a real technique: "Simply use your fingers in a gentle scratching motion to fluff up the curls." It lifts the coat, separates clumps, and moves air down to the skin without touching the curl pattern.
• Longhaired Selkirk? Add a hair pick. CFA again — for long-haired cats a pick helps separate large clumps of curls. Longhairs carry the same thick undercoat under a longer coat, so the clumps are bigger and the undercoat has further to travel to get out.
• Step the comb up during the shed, then step it back down. Through the spring and fall windows, monthly is not enough. Go weekly while it is happening and ease off when it stops.
• Leave the slicker and the undercoat rake alone. The rake is the tempting one, because there genuinely is a thick undercoat down there. It will also pull the curl out straight and leave you with a cat who looks like she has had a rough morning.
• Dry her properly after any bath. A dense double coat holds water against the skin far longer than it looks like it should, and a curled one gives you even less of a visual cue that it is still damp.

When to Call a Professional Groomer

Worth booking when:

• You find a patch on the belly, ruff, or tail base that doesn't comb out in a pass or two. Mats sitting against skin are never a home job with scissors.
• A seasonal shed has outrun what you can do by hand, and the coat is holding hair it should have dropped.
• You have never had a proper look under the coat. A bath and a full dry on a table shows you what the undercoat is actually doing, and it resets a coat that has been quietly accumulating.
• Nails, ears, or a sanitary trim are on the list. None of that is curl-specific, and all of it gets harder the longer it waits.

And on interval, treat the British Shorthair figure above as the default to plan around, rather than letting a problem do the scheduling for you.

Finding a Groomer Who Won't Dry the Curl Straight

The handling side of this breed is easy, by cat standards. CFA describes a cat whose "focus is on you and their idea of kitty heaven is a warm lap," who is "very responsive to their owners" and "more interactive than active," while still noting that the cat must be handled gently. You are not usually booking around fear here.

What you are booking around is finishing. A groomer who works mostly on dogs and straight-coated cats finishes a bath by drying the coat out smooth, because that is what a smooth coat wants. Do that to a Selkirk and you get a technically clean cat whose defining feature has gone missing. It comes back — the curl isn't damaged, just pressed out — but it is avoidable, and the way to avoid it is to say something at booking.

Two questions cover it. Have you groomed a curly-coated cat before, and how do you dry one? The answer you want involves low air and letting the coat spring back on its own, not a high-velocity dryer aimed down the spine.

The directory lists cat-specific groomers by city — ask about curly coats when you call, and mention the undercoat. Plenty of groomers who have never touched a Selkirk Rex will do a lovely job once they know they are working on a double coat in disguise rather than a rex.

Part the curls once a month and the rest takes care of itself. She will go on looking like she rolled out of bed and decided it worked — which, to be fair, she did.
