Vet designed
Designed by emergency vet Dr Duncan Houston. Tested at home by Gary, a Ragdoll who bats the ball round the track and then pretends the scratching was his idea.
How it works

A plastic ball with a bell inside runs in a channel under the rim, with holes over it.

Cats divide into up-scratchers and along-scratchers.

It arrives in one piece: body, printed top sheet, pad, and the ball already in its track.

Round or Square is a question about the floor, not the cat. Open rug, the foot of the sofa arm, the middle of a room: the Round, which has no edge to line up. A corner, a hallway wall, beside the litter tray: the Square, which tucks in flush on two sides.
Both are light. On carpet or a rug they stay put under a scratching cat; on tiles or boards a big cat can shunt the Round along, so give it a rug or choose the Square and put it against a wall. The Square weighs about a third more and is the steadier of the two.
Kittens and old cats: both shapes are low enough to step onto, which is why a flat scratcher is a good first scratcher and a good last one. A kitten also gets the ball; watch that she plays with it through the holes rather than chewing at the rim. A cat who has stopped scratching, or suddenly cannot, is a vet check before she is a new scratcher.

How to

On the rug she rakes, over the worn patch of carpet, by the doormat. A scratcher in the spot she already uses beats a better one in the spare room.

Send it round the track with a finger while she is watching. The bell does the rest; you do not need to do it twice.

Most cats find the ball on day one and the pad within the week. A pinch of catnip on the pad hurries a hesitant cat. Do not carry her to it.

A hand-width a day towards where you want it. Any faster and she goes back to the rug.

When the pad is scratched through it has done its job. Cardboard in the recycling, ball in the next one.
Vet noteDr Duncan Houston, emergency veterinarian
Cardboard scratchers shed, and shredding is normal. A cat who eats the cardboard rather than shredding it should have it taken away and the habit mentioned to your vet, because eating things that are not food has causes. The ball has a bell inside: a ball that has cracked, or a bell that has come out of it, goes in the bin that day, and so does a scratcher whose rim she has chewed open. Scratching that starts suddenly in a new place, or a cat who always scratched and has stopped, or who cries or limps when she scratches, is a vet visit before it is a shopping trip. Scratching itself is not a behaviour problem to remove; it is a claw, a stretch and a scent mark, and this gives it somewhere to go. If any of it worries you, ask your vet.
Why I designed it
Half the cats I see for scratching complaints are not sofa cats at all.

Round design efficiently uses floor space while providing comprehensive functional features. Quality construction withstands the spinning motion without wobbling.
The spinning mechanism combined with scratching surfaces creates engaging claw care. My cat uses this for both maintenance scratching and playful spinning.
FAQ
The ball. It runs in a channel under the rim with holes over it, so a paw through a hole sends it round and the bell rattles as it goes. The scratcher itself stays where you put it, and nothing on it turns or needs winding. The scratch pad is the corrugated cardboard in the middle, sitting a little below the rim so her claws catch the edge of the flutes.
Decide by the floor. Open rug, the foot of the sofa arm, the middle of the room: the Round, which has no edge to line up. A corner, a hallway wall, beside the litter tray: the Square, which sits flush on two sides and runs the track round all four. Same pad, same ball, same price. The Square is about a third heavier, so it is the steadier one under a big cat on a hard floor.
About 35 cm across and about 7 cm high in either shape, which is a pad for the front feet with the back feet on the floor, not a full-length stretching board. A big cat scratches it just the same; she stands over it rather than on it. If she wants the full upward stretch as well, that is what the Scratch Me Happy Scratching Post is for.
For a rug or carpet scratcher, it gives her the same pull in the same place on a surface that takes it better, which is the only approach that works. Put it on the exact spot, leave it two weeks, then move it a hand-width a day if it must move. For a sofa-arm scratcher it helps less: she is scratching upward, and a post at the sofa arm is the right tool. Telling her off changes nothing either way.
The ball runs in a closed channel and the holes are for paws, so in normal play it stays in. The ball has a bell inside: if it cracks or the bell comes out, bin it that day, and take the scratcher away from a cat who chews the rim open rather than scratching the pad. Shredded cardboard is normal; eaten cardboard is a vet conversation.
A light scratcher gets months; a heavy daily scratcher gets weeks before the pad is scratched through, which is the pad doing what it is for. A replacement pad is not sold on its own. When it is done, the cardboard goes in the recycling and the ball goes in the next one. Brush the shreds off; do not glue anything back.
Email hello@purrz.com within 7 days of delivery with a photo and your order number; faulty, damaged or incorrect items are covered and we pay the return shipping when the error is ours. A cat ignoring it in week one is normal: flick the ball once while she watches, a pinch of catnip on the pad, the right spot, and two weeks before you judge it.
