Finally got the armpit mats out. She had those little round mats under both front legs and I was too scared to use scissors. Took two short sessions with treats. No tugging that I could see.

A brush drags the whole knot at once, and that tug is why your cat bolts. Scissors are riskier, because thin cat skin gets pulled up into the mat.
It's how groomers take mats apart by hand. Hollis puts both jobs on one head that turns, so you don't stop to switch tools while your pet's still sitting still.
The curved blades slice the mat into thin strips. Each strip has far less to pull on than the whole knot.
Short strokes from the tips toward the skin lift the strips and the dead undercoat around them.
Flip the head. If the steel comb glides from skin to tip, the mat's gone. If it catches, you've found the next one early.



Catch mats while they're small, a few minutes at a time while she's sleepy. The coat stays long, and the groomer appointment stays optional.

A mat that's tight and flat against the skin, or skin that looks red or raw under it, needs a groomer or your vet. This is for the mats you catch before that.

Maine Coon · The 3-in-1 Mat Comb
Saved me a shave-down. Groomer quoted a full shave for his back legs. I did it myself over a week with this. His coat's still long and he didn't need to be sedated.
Australian Shepherd · The 3-in-1 Mat Comb
One tool instead of four. I had a slicker, a rake, a comb and a mat splitter in a drawer. This does the job of all of them and I don't have to put it down halfway.
Two cats and a golden · The 3-in-1 Mat Comb
Works on the belly. The belly was the part he'd bite me over. Small strokes from the ends and he just lay there. Belly's been mat free for a month.
Persian mix · The 3-in-1 Mat Comb
Watch the technique. First time I went at it like a brush and it pulled. Read the card, held the mat at the base, went from the tips down. Big difference. Four stars because I wish I'd read it first.
Pomeranian · The 3-in-1 Mat Comb
So much undercoat. Bought it for mats, but in shedding season the blade side pulls out more undercoat than our old brush ever did. Less fur on the couch for sure.
German Shepherd · The 3-in-1 Mat Comb
Good for my senior cat. She's 15 and stopped grooming her back end. I do a couple of minutes each evening while she's sleepy and the knots haven't come back.
Senior Ragdoll · The 3-in-1 Mat Comb
Solid build. Head turns and stays put, grip is soft, nothing's bent after two months on a very fluffy dog.
Samoyed · The 3-in-1 Mat Comb
Not for tight mats. Worked great on the newer tangles behind his ears. One old mat right at the skin still needed the groomer, like the page says.
Goldendoodle · The 3-in-1 Mat Comb
The blades curve away from the skin and cut on the inside edge, so the sharp part works inside the mat, not against your pet. Hold the mat at the base with your free hand and work from the tips toward the skin in short strokes. Go slowly near the armpits and belly, where cat skin is thinnest. If the skin under a mat looks red or raw, stop and see your vet.
Both. It's sized for a cat's body as well as a dog's, at 4.1 inches across the head. Long-haired and medium-haired cats get the most out of it. On a short, single coat, use only the comb side.
The blade side is for mats and the dead undercoat around them. Use it only where the coat is knotted or thick with undercoat, then switch to the comb. Don't run the blades over a smooth, healthy topcoat every day.
It handles mats you can get your fingers under: tangles, felted patches and mats a few days or weeks old. A mat that's tight and flat against the skin, or a coat that's matted all over, needs a groomer, usually with clippers. After that, a few minutes with this each week keeps it from happening again.
A deshedding blade and a slicker both pull loose fur out. Neither cuts through a mat, so on a knot they just tug. This splits the mat first, then has a comb on the other side to finish, so it covers mats and shedding in one tool.
Sessions are short, because you're not tugging on the whole knot. Pick a sleepy moment, do one mat, give a treat and stop. There's no noise, so it suits pets that run from clippers.
Pull the fur off the teeth with your fingers after each use. Every few weeks, rinse the head in warm soapy water and dry it fully before you put it away.
