How to Get Your Cat to Use a Scratching Post

Get a post at least 80 cm tall — ideally taller than the cat with its front legs fully stretched — make it heavy enough that it does not move when the cat pulls, cover it in vertical-grain sisal, and put it where the cat already scratches, not in a corner you find convenient. Then reward scratching on the post and never punish scratching on the sofa. That combination works in most homes within two to four weeks.

Why cats scratch, and why the sofa

Scratching does four jobs: it sheds the outer sheath of the claw, it stretches the shoulders and back, it deposits scent from glands between the toes, and it leaves a visual mark at cat eye level. That last one matters — a cat marks the corners of its territory, which is why the sofa arm and the door frame get chosen over a post hidden behind the curtain.

Cats also have surface preferences. Most want a vertical, rough, immovable surface about as tall as themselves. Sofa fabric — woven, rough, anchored to a heavy frame — is an almost perfect match. The post you bought is usually shorter, lighter, and carpeted, which is the wrong combination on all three counts.

What a post has to be

• Height: at least 80 cm, and for a large cat 90-100 cm. The cat must be able to stand on its hind legs, stretch fully and still have post above its paws. A 40 cm post only works for a kitten, and a cat that cannot stretch to full length will go back to the sofa.
• Stability: push the top of the post with one finger. If it rocks, the cat will not use it. A wide base or a weighted bottom is worth more than any feature on the label.
• Material: sisal rope wound vertically, or sisal fabric. Carpet is a compromise — it is the same texture as your floor covering, so it teaches the cat that carpet is fine to scratch. Avoid looped carpet, which catches claws.
• Grain: vertical, so the cat can pull downward. Horizontal sisal on a vertical post gets ignored.
• No bell, no toy on top. A toy at the top invites the cat to grab and hang, and then the post falls over. That is the end of the post.

Placement decides whether it gets used

Put the post where the cat already scratches, or right next to it, even if that is the middle of the living room. Once the habit is on the post, you can move it a little at a time — 20 cm a week.

Also place one where the cat wakes up. Cats scratch after a nap as part of the stretch, so a post beside the sleeping spot gets used without any training at all. In a two-storey home, one post per floor. In a multi-cat house, one per cat plus one, because the post is a scent-marking station and gets contested.

The worst placements: behind a door, in a spare room, in a corner where the cat cannot see the room, and next to the litter box. If the post is somewhere the cat only goes when you carry it there, it will not be used.

Four steps to switch the habit

1. Make the current target less appealing. Double-sided tape, a fitted throw, or a temporary sheet of foil on the sofa arm. Do not remove the cover until the post is in use — the cat needs an alternative, not a vacuum.
2. Make the post obvious. Rub catnip or silvervine on the sisal, or hang a toy on a string from the top and play with the cat so its paws hit the post. Dragging a wand toy up the post is the single most effective trick — it triggers the grab-and-pull motion the post is designed for.
3. Reward every scratch. A treat within two seconds of a scratch on the post. Not after the cat walks away — the reward has to land while the behaviour is happening.
4. Redirect, never punish. If the cat goes for the sofa, pick it up calmly and put it in front of the post, then scratch the post with your own nails. Never spray, shout or tap the cat; punishment teaches the cat to scratch when you are not looking, which is worse.

Expect two to four weeks. Progress looks like longer scratches on the post and fewer on the sofa, not a clean break.

If the cat still prefers the sofa

Check the three failure points in order. Height: is the cat able to stretch fully? Stability: does the post move even slightly? Texture: is it carpet rather than sisal? Fixing any one of these often solves it overnight.

If the cat scratches horizontally, on the floor or a flat mat, it wants a flat scratcher — a corrugated cardboard pad or a sisal mat, placed where it already scratches. Some cats want both orientations, and giving them both is cheaper than a new sofa.

If the cat scratches the sofa in one specific spot every day, put a post directly in front of that spot for three weeks. Once it is using the post, move it 20 cm a week towards where you want it.

Nails, and what not to do

Trim the front claws every two weeks with cat clippers, taking only the clear hook at the tip and avoiding the pink quick. Shorter, blunter claws do less damage while the training takes effect, and trimming is not a substitute for a post — a cat without a post will still scratch.

Soft claw caps work for some cats but need replacing every 4-6 weeks and do not address the need to scratch. Declawing — amputating the last bone of each toe — is banned in much of Europe and several US states, and is associated with chronic pain, biting and house-soiling. There is no behavioural problem for which it is the answer.

For cats that scratch door frames and wall corners, the same rules apply: a post beside the door frame, a temporary cover on the frame, and rewards. And if a cat suddenly starts scratching a lot more, or scratches at its own face and ears, that is worth a vet check — the health section covers the itch and pain causes, and the rest of the daily routine sits under care.
