Cats scratch to stretch and to leave a scent mark, and they are particular about the surface. Corrugated cardboard is the one most cats take to without any persuasion, because the layered edge shreds and gives way under the claw in a way that carpet and tightly wound sisal never quite do. This one folds like a concertina, so it lies out as a long flat strip or curls round into a ring.

That folding construction is what makes it versatile. Opened flat it sits along the base of a sofa or under a windowsill; bent into a circle it becomes a small arena with a track running round the middle, and a bell ball drops into that track for a cat to bat at and chase. Pairing the scratching surface with something that moves is sound design, because drawing a cat to the scratcher in the first place is the hard part.

On the product name. The manufacturer lists this item with a reference to magnetic attachments. What actually arrives is a folding corrugated scratcher with a bell ball, and there are no magnets involved anywhere. Cardboard sheds as it is used, so expect to hoover around it.

Who it's for: Cat owners who want an inexpensive cardboard scratcher that also gives a bored indoor cat something to chase.
