One of the most common complaints cat owners have is that they've bought a scratching post and their cat simply won't use it. Meanwhile, the corner of the sofa continues to deteriorate. The post sits untouched. The cat seems to look at it with active disdain.
This is frustrating, but it's almost never a case of a cat that simply won't scratch appropriately. Cats need to scratch — it's hardwired. If they're ignoring the post, the post has a problem. Usually several. The good news is that the reasons are well understood and almost always fixable.
The seven most common reasons
It's in the wrong place
This is the single most common reason a scratching post goes unused. Cats scratch where they spend time — usually wherever their owner is, or near favourite sleeping spots. A post positioned in a spare room, a corner of the hallway, or anywhere "out of the way" is positioned for your convenience, not your cat's. They want to scratch in the centre of their territory, not at the edges of it.
Move the post to where your cat already spends time — beside the sofa they're scratching, near their sleeping spot, or in the main living room. Placement matters more than any other factor.
It's not tall enough
Cats scratch as a stretch behaviour as much as a claw behaviour. To get the full benefit of a scratch, they need to fully extend — forelimbs, shoulders, back. Most budget posts are 45–65cm tall. Most adult cats need 90–100cm of height to fully extend. A post that's too short simply doesn't provide the stretch that makes scratching satisfying, so the cat goes elsewhere to find a surface that does. Your sofa arm, being tall and solid, usually qualifies.
Measure your cat at full stretch and choose a post that comfortably exceeds that length. For most adult cats, look for 90cm minimum. If you already have a post that's too short, there's no easy fix — it needs replacing with a taller one.
It wobbles
Scratching requires resistance. A cat needs to push against something solid to get the physical benefit of the scratch — if the post moves when they lean into it, the scratch is unsatisfying and potentially alarming. Cats quickly learn that a wobbly post isn't worth using and revert to surfaces that don't move, like your walls or furniture. Even a post that only tips slightly will often be abandoned.
Test your post by pressing firmly from the side at the point where your cat scratches. It should not move at all. If it does, a non-slip mat under the base can help, but a post with a genuinely heavy, wide base is the real solution. This is a design problem, not a fixable one with the same post.
The texture is wrong
Cats have specific preferences about scratching surfaces. They need enough resistance that the outer claw sheath catches and pulls away — too smooth and nothing happens; too rough and it's uncomfortable. Natural fibres like sisal and jute sit in the right range for most cats. Carpet surfaces are often too similar to flooring cats are already discouraged from scratching, creating confusion. Smooth wood, plastic, and soft fabrics are usually ignored entirely.
If your post has a carpet or smooth surface and your cat ignores it, the texture may be the issue. Try wrapping a section with natural sisal or jute twine to see if the cat responds before investing in a new post entirely.
The surface is worn out
A scratching post surface that's been used down to a flat, smooth state no longer provides resistance. Paradoxically, cats are often more attracted to a lightly worn surface — their own scent marks are there and the texture is broken in. But a heavily worn, flat surface is as useless to a cat as a smooth one. They'll seek out better texture elsewhere, which usually means your furniture. This is one of the most overlooked reasons for post abandonment, because the post looks physically fine from across the room.
Get close to the surface and check whether the texture is still providing resistance. If the sisal or jute feels flat and smooth underhand, the surface needs replacing. On most posts this means replacing the whole product. On Culm, it means ordering a new sleeve.
It's too new
This sounds counterintuitive but is genuinely common. A brand-new post has no scent on it — no claw marks, no pheromone deposits from the cat's paw glands, nothing to signal that this is a scratching site. A cat that has been using the sofa for months has built up substantial scent marking on it. From a cat's perspective, the sofa is clearly a scratching site (it smells like one) and the new post isn't (it doesn't smell like anything). It can take time for a cat to claim a new post.
Rub a small amount of catnip into the base of the post, or gently press your cat's paws against it to transfer scent. Placing it immediately next to the sofa they currently scratch also helps — they'll investigate it as part of their normal route. Give it two to three weeks before concluding it isn't working.
Your cat prefers horizontal scratching
Most scratching posts are vertical, but some cats strongly prefer to scratch horizontally — lying on their side and pulling back along a flat surface, or kneading a horizontal pad. This is a genuine behavioural preference, not a training problem. A cat that consistently scratches flat surfaces (carpets, rugs, flat sofa arms) rather than vertical ones probably prefers the horizontal orientation and will always ignore a vertical post regardless of its other qualities.
Add a flat cardboard scratcher or horizontal sisal pad alongside a vertical post. Many cats that "won't use a scratching post" will immediately use a horizontal scratcher — the format matters as much as the material.
"If your cat is scratching somewhere else, they're not misbehaving. They're using a surface that works for them. The question is what's wrong with the post you've provided."
What to do if you've tried everything
If you've addressed placement, height, stability, texture, and age, and your cat is still ignoring the post, it's worth ruling out a couple of less-common factors.
Stress or change in routine. Cats under stress scratch more — and often in different places. A new pet, a house move, a change in working pattern, or building work nearby can all disrupt established scratching behaviour. In these cases the scratching is a symptom of something else and the post choice is secondary.
Pain or joint issues. Older cats or cats with arthritis may avoid a post that requires them to raise their forelimbs. If your cat has recently stopped using a post they previously used regularly, this is worth discussing with a vet.
The post genuinely isn't suitable. Not every post works for every cat. If you've tried a vertical post in the right location with the right surface and your cat consistently ignores it, they may simply need a different format — horizontal, angled, or a different material entirely. Some cats will only scratch wood; some will only scratch certain fibres. A small amount of experimentation is sometimes unavoidable.
By far the most frequent combination we encounter: post too short, placed too far from where the cat spends time, surface worn flat. Fix all three and most cats that have been "ignoring the post" will start using it within a week. The post usually isn't the problem — its location, height, and surface condition are.
