Why cats scratch the sofa, and what to do

A cat does not scratch out of stupidity: it marks, it maintains its claws and it stretches. Three real needs.

Forbidding the sofa corner without offering better simply moves the problem to the armchair.

A post that tips is abandoned within two days. Weight matters more than price.

In the shop: Anti-scratch tape — the sofa corner, protected and Accordion scratcher — it unfolds where the cat goes.

The corner of a sofa combines everything a cat looks for: a vertical surface to stretch out fully against, a texture that grips enough to offer resistance, and above all a central position in the room. Marking is only worth doing where it is seen and smelled — a cat does not mark behind a wardrobe.

Then there is scent. The pads deposit pheromones, and an already-marked spot calls for the next marking. That is why cleaning without neutralising is not enough: the cat returns to exactly the same point.

Finally there is timing. Most scratching sessions follow waking, because stretching is part of the ritual. A post placed far from the sleeping spot will not be used at that moment — and that is precisely the moment that counts.

The first is to make the corner uninteresting. Smooth transparent tape removes the grip: without resistance, the movement gives nothing back. It is not a punishment, it is an answer to a physical question.

The second is to put something more satisfying beside it. Beside it, not across the room: the cat will not go looking for a substitute three metres away. Thirty to fifty centimetres from the attacked point is the right distance.

Taken separately, these two moves fail. Tape alone shifts the scratching elsewhere. A post alone, placed far away, stays ignored. Together they settle the question in one to two weeks in most cases.

A third action helps: trimming the claw tips every three to four weeks. It does not remove the need to scratch, but it limits damage during the transition.

Height first. An adult cat stretches over sixty to seventy centimetres. A forty-centimetre post forces it to hunch, and it goes back to the sofa, which is the right size.

Weight next, and this is the most neglected criterion. A post that moves when the cat pulls on it becomes unusable: the animal wants a stable anchor, and an unstable object tells it this is not one. A wide, heavy base beats a careful finish.

Material last. Sisal frays along the grain of the claws and gives exactly the resistance sought. Carpet poses a different problem: it looks like a rug, and a cat that learns to scratch carpet will scratch the rugs in your home too. Corrugated cardboard works well flat, less so vertically.

And one detail that changes everything: a new post has no smell. Rubbing it with a little catnip, or transferring scent by stroking the cat then handling the post, speeds adoption noticeably.

With an adult cat set in its habits, expect one to three weeks for a full transfer, provided both moves are made at the same time. With a kitten, a few days.

The sign it is working is not that sofa scratching stops overnight: it is that its frequency drops, and that sessions appear on the post after waking. If after two weeks the post has never been used, it is badly placed or badly sized — not refused.

One point not to overlook: several cats in a home need several posts. A single one becomes a territorial issue, and the subordinate cat returns to the sofa for lack of access.
