Best Cat Undercoat Brushes & Rakes for 2026
The undercoat is the dense layer that actually tufts up your couch — and most brushes glide right over it. Here are the rake and brush types that reach it, scored by our Fit Analysis and matched to coat type.

The undercoat — the soft, dense layer under the guard hairs — is where shedding and matting actually come from, and an ordinary brush barely touches it. To reach it you need a tool with either a fine, close-set edge (a deshedding tool) or long, rounded pins (an undercoat rake).
Match the tool to the coat: short and medium coats do well with a deshedding edge used weekly; long or double coats need a rake first to break up the dense layer, then a slicker to finish.
One rule matters more than the tool: never dig at a mat with a rake. Rakes and deshedding edges are for loose undercoat, not tangles — a mat gets combed apart or cut out, gently.
Why the undercoat needs its own tool
A cat’s coat is two layers. The guard hairs on top are the long, sleek ones you see. Underneath sits the undercoat — a soft, dense layer of shorter fur that insulates the cat and, when it loosens, is exactly what ends up on your couch and clumped into mats.
Most brushes are built for the top layer. A pin brush or a bristle brush glides across the guard hairs and makes the coat look tidy, but the loose undercoat stays put. That is why a cat can look well-groomed and still shed constantly: the fur coming out is below the layer the brush is touching.
Reaching the undercoat takes a tool designed to pass through the guard hairs — either a fine deshedding edge that catches loose fur close to the skin, or a rake with long pins that rotate down into the dense layer.
Which tool actually reaches the undercoat
| Tool type | How it reaches the undercoat | Best coat | Watch out for |
|---|---|---|---|
| Deshedding edge (FURminator-style) | Fine stainless teeth catch loose undercoat below the guard layer | Short to long, single or light double coats | Pressing too hard — the edge can scrape skin |
| Undercoat rake | Long rounded pins rotate through the dense layer and lift packed fur | Thick double coats, long hair | Not for mats — it pulls, it doesn’t cut |
| Dematting rake / comb | Bladed teeth split tangles before they set into mats | Long hair prone to knots | Skin nicks near belly and armpits — go slow |
| Slicker brush | Fine bent wires lift the undercoat a rake has already loosened | All coats, as a finisher | Wire tips dragged on bare skin |
| Grooming glove | Silicone nubs pull surface and top-undercoat fur painlessly | Any cat, especially brush-averse ones | Surface only — won’t clear the deep undercoat |
Match the tool to your cat’s coat
Short and medium coats. A deshedding edge used once or twice a week does almost all the work. Short-haired cats do have an undercoat — it is just shorter — so a fine edge still pulls loose fur a bristle brush leaves behind. You rarely need a rake.
Long hair and thick double coats. Here the order matters. Start with an undercoat rake to break up and lift the dense packed layer, then finish with a slicker to collect what the rake loosened. During seasonal blow-outs (spring and fall), the undercoat sheds in volume and this two-step becomes a weekly ritual.
The brush-averse cat. If your cat leaves the moment a rigid tool appears, tolerance beats technique. A grooming glove reads as petting and clears the surface, and a calmer cat lets you do a short rake pass afterward. A tool your cat refuses removes zero fur.
The honest caveats
We score tools on the MeowTested Fit Analysis — a structured research framework, not an in-home lab test — and the same discipline applies to how you use them.
- Over-deshedding damages the coat. A deshedding edge removes loose undercoat; run it over the same spot again and again and it starts thinning healthy fur and irritating skin. A few light passes is the whole job.
- Rakes are not for mats. A formed mat is tight to the skin — raking it drags the skin and hurts. Work a mat apart with a dematting comb and your fingers, or have a groomer or vet shave it.
- A tool won’t out-groom a health problem. Sudden heavy shedding, bald patches, or scabs are a vet question, not a brush question. Grooming manages a normal coat; it doesn’t fix an abnormal one.
The undercoat kit we’d buy
A short kit, not a drawer full of gadgets. Start with the deshedding edge; add the rake only if your cat is long-haired or double-coated.
FURminator deShedding Tool (Long Hair)
The fine stainless teeth reach the loose undercoat below the guard hairs. The single highest-yield tool for most cats — short strokes, light pressure.

For the days your cat won’t sit for a rake. It reads as petting and clears the surface — not an undercoat tool, but the one that keeps grooming happening at all.

What’s the difference between an undercoat rake and a deshedding tool?
A deshedding tool has a fine, close-set stainless edge that catches loose undercoat close to the skin — best on short-to-medium coats. An undercoat rake has longer, rounded pins that rotate through a thick, dense layer to lift packed fur — best on long or double coats. Many long-haired cats benefit from both: rake first, deshedding edge or slicker to finish.
How often should I use an undercoat rake on my cat?
Once or twice a week for most cats, and more often during spring and fall seasonal shedding when the undercoat blows out. A few light passes per session is enough — going over the same area repeatedly thins healthy fur and irritates skin.
Can I use an undercoat rake on a matted cat?
No. A rake is for loose undercoat, not tangles. Dragging a rake through a mat pulls on skin that the mat is already tightening. Work mats apart gently with a dematting comb and your fingers, or have a groomer or vet shave a tight one. Then use the rake to prevent new mats from forming.
Do short-haired cats have an undercoat?
Most do — it is simply shorter and less dense than a long-haired or double-coated cat’s. That is why short-haired cats still shed noticeably, and why a fine deshedding edge pulls loose fur that a bristle brush leaves behind. Short-haired cats rarely need a full undercoat rake, though.
