Why cats scratch furniture and how a scratching post fixes it

Cats scratch furniture because scratching is a normal, necessary behaviour, and the sofa happens to be the best-placed, most satisfying surface in the room. They are not being spiteful and they cannot be trained out of scratching altogether. What you can do is give them a better option in the right place, make the furniture less appealing for a few weeks, and let the habit move. This guide explains why a cat scratching furniture is doing it, and how to fix it without punishment.

Why cats scratch in the first place

Scratching does four jobs at once.

• Claw maintenance. Scratching strips the worn outer sheath from each claw, exposing the sharp new one underneath. Those crescent-shaped husks you find on the carpet are the evidence.
• Stretching. A full-height scratch stretches the shoulders, back and forelegs. Cats do it after waking, which is why the scratched furniture is usually near where they sleep.
• Scent and visual marking. Glands between the paw pads leave scent, and the shredded surface leaves a visible mark. Cats scratch at territorial boundaries: doorways, the arm of the sofa, the side of the bed.
• Stress relief. Cats scratch more when excited, frustrated or anxious. A sudden increase in scratching often follows a change at home: a new pet, a move, visitors, building work.

Because every one of these is a need, not a habit, removing the opportunity to scratch doesn't work. Replacing it does.

Why the sofa wins against the scratching post

If you already own a scratching post and the cat still prefers the sofa, one of these is almost always the reason.

What the cat wants	What the sofa offers	What a bad post offers
Height for a full stretch	70–90cm sofa arm	45cm post
Stability under force	Heavy, doesn't move	Light base, tips or slides
Satisfying texture	Woven fabric that shreds	Smooth carpet or soft plush
Location	Centre of the living room, by the sleeping spot	Hallway or spare room

Fix those four things and the furniture problem usually fixes itself within two to four weeks.

How to choose a scratching post that gets used

Height

The post must be taller than the cat at full stretch. For an average adult cat that means 60cm minimum; for large breeds, 80–90cm. Short posts get a half-hearted swipe and are then ignored.

Stability

A cat pulls hard. The base should be heavy and at least 40cm across for a 60cm post, wider for taller ones. If the post wobbles when you push it, the cat will go back to the sofa, which doesn't wobble.

Texture

Sisal rope is the standard and most cats like it. Sisal fabric is tougher and shreds in a more satisfying way. Corrugated cardboard works for horizontal scratchers. Avoid posts covered in the same soft carpet as your floors; you're teaching the cat that carpet is for scratching.

Orientation

Watch where your cat scratches now. Up the arm of the sofa means they want a vertical post. Across the carpet or the top of a rug means they want a horizontal or angled scratcher. Many cats want both. Browse our cat scratching posts and scratchers by orientation and height, or choose a cat tree that combines posts with a sleeping perch.

Where to put the scratching post

This is the step most people get wrong. The post goes next to the furniture being scratched, within 50cm of the sofa arm, facing the room. The cat has chosen that spot for territorial reasons, and the post needs to be a better option in the same spot. Once the cat has switched reliably, you can move the post a few centimetres a day to a more convenient position.

Also put one near where the cat sleeps, because scratching follows waking. If you have two cats, provide two posts in different places.

Making the furniture less attractive for a few weeks

While the new post is bedding in, make the old surface a worse option. These are temporary.

1. Double-sided sticky tape on the scratched area. Cats dislike the feel on their pads. Use a furniture-safe tape and test on a hidden spot first.
2. A throw or fitted cover over the sofa arm, in a smooth fabric that doesn't shred.
3. Move the post into the exact spot and block the old one with it where possible.
4. Reward scratching on the post. Treats, fuss, a wand toy dragged up the sisal. Our cat toys include wand toys that are ideal for this.

Keep the tape and covers on for three to four weeks after the last furniture scratch, then remove them gradually.

What not to do

• Don't punish. Shouting, water sprays and clapping teach the cat to scratch when you're not in the room. They also add stress, which increases scratching.
• Don't declaw. It is illegal in the UK under the Animal Welfare Act and causes lifelong pain and behavioural problems.
• Don't rely on claw caps. They need replacing every few weeks and don't address the need to scratch.
• Don't buy on looks. A post that matches the decor but wobbles or is too short is a waste of money.

Trimming the claw tips every two to three weeks reduces damage during the transition. Ask your vet or a groomer to show you once if you're unsure.

When to see a vet

Normal scratching is a few seconds, a few times a day. If your cat is scratching compulsively, scratching at themselves, limping, or scratching far more alongside hiding, over-grooming or toileting outside the tray, see your vet. Pain, skin problems and anxiety all show up as changed scratching.

Cat scratching furniture FAQs

Why does my cat scratch the sofa when there's a scratching post?

Usually because the post is too short, too wobbly or in the wrong room. Move a tall, heavy post next to the sofa and the cat will switch.

How long does it take to stop a cat scratching furniture?

With the right post in the right place and the furniture covered, most cats switch within two to four weeks.

Do cats grow out of scratching?

No. Scratching is lifelong. Older cats scratch less vigorously but still need a post.

Does a cat tree stop furniture scratching?

Often, if its posts are tall, sisal-covered and the tree is positioned next to the furniture. A tree with short posts between platforms may need a separate floor post alongside it.
