Cats scratch to shed the outer sheath of their claws, to stretch their back and shoulders, and to leave scent and visual marks. It is a need, not a habit you can train away — but you can absolutely redirect it. The trick is a post that is better than the sofa from the cat’s point of view.
Height and stability come first
Watch a cat scratch the arm of a sofa: they reach up as far as they can and pull down with their whole weight. A short post that rocks when they lean on it will be ignored. Look for a post of at least 80 cm with a wide, heavy base. If the post wobbles when you push the top with a finger, it will not satisfy a cat.
Materials cats prefer
- Sisal rope or sisal fabric — rough, durable and the clear favourite of most cats. Sisal fabric wears more evenly than rope.
- Corrugated cardboard — cheap, loved by many cats for horizontal scratching, but sheds confetti and needs replacing.
- Carpet — often used on cheaper posts, but it can teach cats that carpet is for scratching, which rarely ends well.
- Bare wood or bark — appeals to some cats and looks good, but check it does not splinter.
Vertical, horizontal or both?
Some cats scratch upwards on vertical surfaces; others drag horizontally across rugs and doormats. Many do both. Offer one of each to start, then invest in more of the type your cat uses. Angled scratchers are a good compromise for cats who seem undecided.
Where to put it
Location matters as much as the product. Put the post right next to the spot your cat currently scratches — in front of the sofa arm, by the doorframe — and near where they sleep, because cats love a stretch and scratch on waking. Once the cat is using the post reliably, you can move it a few centimetres a day towards where you would prefer it to live.
Moving the habit off the furniture
- Place a tall, stable post directly beside the damaged area.
- Make the furniture less appealing temporarily: double-sided sticky tape, a tightly fitted throw or a sheet of foil on the favoured spot.
- Rub catnip or valerian on the post, or dangle a wand toy against it so the cat’s claws catch the surface.
- Reward every use of the post with a treat or praise. Never punish scratching — it increases stress and usually makes it worse.
- Keep claws trimmed if your cat tolerates it; it reduces damage during the transition.
Frequently asked questions
Why does my cat ignore the scratching post?
The most common reasons are that it is too short, it wobbles, it is covered in a material the cat dislikes, or it is in a corner the cat never visits. Try moving it next to where they already scratch first.
How many scratching posts does a cat need?
At least one tall vertical post plus one horizontal scratcher, with more spread around a larger home or for multiple cats.
How often should I replace a scratching post?
When the surface is shredded to the core or the post becomes unstable. Heavily used sisal often lasts a year or two; cardboard scratchers need replacing every few months.
Can I make a scratching post more attractive?
Yes: rub catnip into it, play with a wand toy against the surface, and put it near a sleeping spot or window. A little pre-scratched texture also helps — a pristine post can be less inviting.
