Stop a cat scratching the furniture — without a fight

A cat scratching the sofa isn't being spiteful or badly behaved. It's doing something it's built to do and can't simply be told to stop.

Scratching marks territory, keeps the claws in condition and stretches the whole body. The realistic goal isn't to end it but to move it — to give the cat a target it prefers to your furniture. Every approach that works is a version of that, and every approach that fails is an attempt to remove the behaviour itself.

Why cats scratch

Scratching serves three purposes at once. It leaves a scent and a visible mark that says the territory is claimed, it sheds the worn outer sheath of the claw, and it stretches the muscles of the legs and back.

It's hardwired rather than learned, which is why scolding a cat for it achieves nothing but a warier cat. A cat that has been shouted at doesn't stop scratching; it scratches when you're out, which is worse for you and no better for the sofa.

Worth noticing the territorial half of that list, because it explains a lot of otherwise baffling behaviour. Scratch marks are a message left for other cats, which is why the most-scratched spot in a house is so often beside a door, a window or the route everybody takes through a room. The cat isn't choosing your favourite chair to annoy you. It's choosing the most visible surface on the main road.

Give a better target

Provide scratching posts that actually suit a cat: tall and sturdy enough not to wobble when leaned on, in both upright and horizontal forms, covered in something satisfying like sisal.

Height matters more than anything else. A cat scratching properly extends its whole body, so a post shorter than the cat at full stretch is a post that doesn't do the job — and most of the cheap ones sold in supermarkets are exactly that. If your cat ignores a post, the height is the first thing to check.

Stability comes second and is nearly as important. A post that rocks when a cat puts its weight into it will be abandoned after two attempts, because the whole point is to pull hard against something that doesn't move.

Place them where the cat already scratches and near where it sleeps, since cats love to scratch on waking. Reward the cat for using them, and most will choose the post over the sofa.

Every cat has a preference

Cats are surprisingly particular about surface and orientation, and a post that one cat loves another will ignore completely.

Some scratch vertically, standing on their back legs against a tall surface. Some scratch horizontally on the floor, on a mat or a flattened box. A few do both. If your cat is working on a carpet or a rug rather than a chair arm, it's telling you it wants a horizontal option, and no amount of vertical posts will satisfy it.

Material matters too. Sisal rope is the usual recommendation and suits most cats, but plenty prefer corrugated cardboard, and a few will only touch carpet or bare wood. Cardboard has the advantage of being cheap enough to buy three and find out which shape gets used.

If you're not sure, put out one of each for a fortnight and watch. The cat will answer the question far more reliably than any advice, including this.

Make the furniture boring

While you redirect, make the targeted furniture unrewarding: double-sided tape, a temporary cover or foil on the spot cats dislike underfoot, with a good post placed right beside it.

The placement is the part people get wrong. Covering the sofa arm and putting the post across the room teaches the cat that this corner is closed and offers nothing in exchange. The post needs to be within a whisker of the old spot — close enough that a cat heading for the arm meets the post first — and can be moved a few inches a week afterwards if you'd rather it lived elsewhere.

Keep the claws trimmed to blunt the damage. This is redirection rather than punishment, and the aim is simply that the post wins.

Never declaw

Declawing isn't a nail trim. It amputates the last bone of each toe, causes lasting pain and can leave a cat with long-term behaviour and litter-box problems, which is why it's banned in much of the world.

It removes the cat's defences and does nothing to meet the need that drove the scratching. A declawed cat still wants to scratch, still wants to mark and stretch, and now does it without the equipment — which is why the behavioural fallout so often shows up as biting instead.

If the damage is genuinely unmanageable, the humane alternatives are nail caps glued over the claws, regular trimming, and more and better posts. All three take effort and none of them is surgery.

When scratching suddenly increases

A change in how much a cat scratches is usually a change in something else, and it's worth reading as information.

New cat in the house, new cat outside the window, a move, a baby, a change in who lives there: anything that makes a cat feel less certain about its territory tends to produce more marking, and scratching is marking. The scratching isn't the problem in those cases — it's the symptom, and adding posts helps while the underlying thing settles.

An older cat that starts scratching in new places, or stops using a post it has used for years, may be finding the stretch uncomfortable. Arthritis is extremely common in older cats and very easy to miss, and a horizontal scratcher at floor level is often used gratefully by a cat that can no longer reach up.

Kittens, and getting it right from the start

A kitten will scratch whatever it finds first, and what it finds first tends to become the habit. That makes the first few weeks unusually cheap to influence.

Put posts out before the kitten arrives, in the rooms it will actually be in rather than in a corner nobody visits. Reward every use you see, in the moment. And accept that a kitten will test everything in the house at least once — that isn't a failure of training, it's how a small animal finds out what the world is made of.

There's one more placement worth knowing about, and it costs nothing. Cats scratch on waking, reliably and almost immediately, which means a post beside the place your cat sleeps will get used several times a day without any encouragement at all. It's the single highest-return position in the house.

How many posts

More than one, and more than you think. The usual guidance for a multi-cat household is a post per cat plus a spare, positioned so that no cat has to pass another to reach one.

Even for a single cat, two or three in different rooms works far better than one excellent post in the hall. Cats scratch where they are rather than travelling to do it, and the sofa's great advantage is that it's in the room where everybody sits.
