If your cat has chosen the arm of your sofa, you are not dealing with bad behaviour. You are dealing with three needs stacked on top of each other: claw maintenance, a full-body stretch, and scent marking. The sofa arm happens to be the best object in the house for all three. Shouting at a cat for using it is like telling someone off for using the stairs.
This guide is what actually works, in the order it works, based on what cat owners complain about most.
1. Work out which kind of scratching you are seeing
Vertical scratching — reaching up, pulling down — is a stretch plus a scent mark. Horizontal scratching, usually on carpet or a doormat, is more about claw maintenance. A cat that does both needs two surfaces, and a single scratching post covers only one of them.
Watch for a day. Note the height of the claw marks and whether they run up and down or side to side. That tells you what to buy and where to put it.
2. Put the alternative in the same place, not a better place
The single most common mistake: buying a scratching post and putting it in the corner of the room where it looks tidiest. Cats scratch near where they sleep and where they greet you — those are the two places worth covering first.
A cut-to-size scratch mat exists for exactly this reason: you trim it to the patch your cat already uses and fit it there, rather than hoping they relocate.
3. Match the direction and cover the whole patch
If the damage runs up and down the sofa arm, fit the replacement surface vertically. And cut it slightly larger than the scratched area — covering half the patch simply moves the problem to the exposed half.
4. Give them a reason to investigate — once
A pinch of catnip worked into the new surface restores novelty for roughly two cats in three. Use it sparingly and not every day; heavy use dulls the response. A single top-up pouch lasts months if you use it as a reset rather than a routine.
5. Make the sofa boring, do not make it frightening
Double-sided tape and foil on the old spot work because the texture is unpleasant, not because they scare the cat. Never use sprays, noise deterrents or anything that startles: a frightened cat does not stop scratching, it scratches somewhere you cannot see.
6. Keep the claws short
A cat with overgrown claws scratches more, because the outer sheath needs shedding. Regular trimming reduces the frequency; it does not remove the behaviour, and nothing should.
What does not work
- Moving the post later. Once a cat accepts a surface, moving it restarts the clock. Decide the position first.
- One surface for two cats. In a multi-cat home the surface becomes contested. Two corners, two surfaces — which is why our Two-Cat Set exists.
- Declawing. Illegal in the UK and rightly so.
How long it takes
Most cats investigate a new surface within a day and settle into it over two to four weeks. If after a month a fitting is genuinely unused, move it to the second place on your list — not to the place you would prefer.
