You come downstairs to find your sofa arm shredded. Again. The fabric is hanging in strips, the foam underneath is exposed, and your cat is sitting on the coffee table looking at you with zero remorse. You’ve tried spraying the sofa with citrus, sticking double-sided tape on it, shouting “no” — none of it has worked. Your cat doesn’t scratch the sofa to annoy you. They scratch it because they’re a cat, and scratching is one of the most fundamental things cats do. The good news: you can redirect this behaviour without giving up on your furniture.

Why Cats Scratch (And Why You Can’t Stop It)
Scratching is not a behavioural problem. It’s normal, healthy cat behaviour that serves multiple essential purposes.
Claw Maintenance
Cats scratch to shed the outer sheath of their claws, revealing the sharp new claw underneath. If they can’t scratch, these sheaths build up and the claws can become overgrown and uncomfortable. You’ll sometimes find translucent claw husks near their scratching spots — that’s the shedding process working correctly.
Territory Marking
Cats have scent glands in their paw pads. When they scratch a surface, they’re leaving both a visual mark (the scratches) and a scent mark that signals “this is mine” to other cats. This is why cats often scratch prominent, visible surfaces — they want the mark to be seen and smelled. Your sofa arm is at nose height for other cats. It’s the perfect signpost.
Stretching
Watch your cat scratch. They reach up, dig in, and pull down with their full body weight. This stretches the muscles in their shoulders, legs, and paws — essentially a full-body stretch. Cats need this, especially after sleeping (which they do for 15 hours a day).
Emotional Regulation
Cats scratch when they’re excited, anxious, or frustrated. A cat that scratches when you come home is expressing excitement. A cat that scratches more during changes in routine may be stressed. The Cats Protection scratching guide explains these emotional triggers well.
The point is: you cannot and should not try to stop your cat scratching entirely. You can only redirect where they do it.
The Three Things Every Cat Needs to Stop Scratching Furniture
If your cat is scratching your furniture, at least one of these three things is missing:
- An appropriate scratching surface they prefer over the furniture
- Correct placement of that surface near the furniture they’re targeting
- Positive association with the scratching post (not punishment for using the furniture)
Get all three right and most cats will voluntarily switch to the post within 1-2 weeks. Get any of them wrong and no amount of deterrent spray will save your sofa.
Choosing the Right Scratching Post
Not all scratching posts are created equal. The cheap, carpet-covered posts from the supermarket pet aisle are why many people think their cat “doesn’t like scratching posts.” The post was wrong, not the cat.
Material
- Sisal rope or sisal fabric — the gold standard. Cats love the resistance and the texture. Sisal gives them a satisfying grip and shreds in a way that feels productive. Most cats prefer this over any other material
- Cardboard — surprisingly effective and cheap. Corrugated cardboard scratchers (the flat, angled ones) are popular because the texture is different from furniture. Cats who ignore rope posts sometimes love cardboard
- Wood — logs, bark, or untreated wood posts. Natural and appealing to cats who go for wooden furniture. If your cat scratches your oak table legs, they might prefer a wood scratcher
- Carpet — avoid this. Carpet-covered posts teach your cat that carpeted surfaces are for scratching, which transfers directly to your carpet. It’s also the least satisfying texture for most cats
Height
A scratching post must be tall enough for your cat to fully stretch while using it. This means at least 80cm for an average adult cat. Those 30cm-tall posts from Pets at Home are useless for adult cats — they can’t get a full stretch, so they go back to the sofa arm instead.
Stability
This is the number one reason cats reject scratching posts. If the post wobbles or tips when they lean into it, they won’t use it. They need to brace against it with their full body weight. Heavy, wide-based posts or wall-mounted options are far more successful than lightweight freestanding ones.
Recommended Posts
- SmartCat Ultimate Scratching Post (about £35-40 from Amazon) — 80cm tall, heavy base, sisal, virtually wobble-free. The single most recommended scratching post in every UK cat behaviour community. Our cats have had one for three years and it’s still solid
- PetFusion Ultimate Cat Scratcher Lounge (about £30-35) — a large, curved cardboard scratcher that doubles as a lounge. Cats love lying on it as well as scratching it
- IKEA LURVIG scratching mat (about £6) — a sisal mat you hang on a wall or furniture leg. Cheap, effective, and surprisingly popular
Placement Matters More Than the Post Itself
You’ve bought the perfect scratching post. You’ve put it in the corner of the spare room where it won’t be in the way. Your cat has never been in the spare room. The post goes unused, and the sofa continues to take damage.
Place It Where They’re Already Scratching
If your cat scratches the sofa arm, put the scratching post right next to the sofa arm. Literally touching it. The cat scratches there because it’s a high-traffic, socially significant spot — not because they’ve specifically chosen your sofa. They need a scratchable surface in that location.
Near Sleeping Spots
Cats stretch and scratch immediately after waking up. Place a scratcher near their favourite sleeping spots and they’ll use it as part of their wake-up routine.
Near Entry Points
If your cat scratches by the front door or the cat flap, they’re territory marking at a boundary. Place a scratcher there.
Common Mistake: Hiding the Post
People put scratching posts out of sight because they’re ugly. But cats scratch in prominent locations — that’s the whole point (territory marking). A post hidden behind a chair in a room nobody uses will be ignored. Accept that the post needs to be where the cat wants to scratch, not where you want it.
Once your cat is reliably using the post (give it 2-4 weeks), you can gradually move it a few inches per day to a more convenient location. Don’t move it suddenly.
How to Redirect Your Cat to the Scratching Post
Positive Reinforcement
- When your cat uses the post, give immediate praise and a treat. Every time. Consistency matters
- Rub catnip on the post — about 70% of cats respond to catnip, and it creates a positive association with the surface
- Play with a feather toy near the post, dragging it up the surface so your cat reaches up and makes contact with the sisal. Once their claws engage, instinct takes over
Never Punish Furniture Scratching
- Don’t shout, spray water, or physically move your cat away from furniture. Punishment creates fear and stress, which often increases scratching behaviour (remember: cats scratch when anxious)
- Don’t grab their paws and put them on the post. Cats hate having their paws manipulated, and this creates a negative association with the post
- Simply redirect — pick up a toy, make the post more interesting, reward post use
How Long Does Retraining Take?
Most cats will start using a well-placed, appropriate scratching post within 1-2 weeks. Some stubborn cats take a month. If your cat hasn’t touched the post after a month despite correct placement and material, try a different surface type (switch from rope to cardboard, or try vertical vs horizontal orientation — some cats prefer to scratch horizontally).
Deterrents That Actually Work
These buy you time while your cat learns to prefer the post.
Double-Sided Sticky Tape
Cats hate the sensation of sticky surfaces on their paws. Apply sticky tape (or purpose-made “Sticky Paws” strips, about £8 for a pack from Amazon) to the furniture surfaces your cat targets. This makes the furniture unpleasant without punishing the cat. Remove once they’re reliably using the post — usually after 2-4 weeks.
Aluminium Foil
Drape foil over the scratched area. Most cats dislike the texture and the sound. Not the most attractive solution, but effective as a temporary measure.
Physical Furniture Covers
A loose throw or furniture cover over the target area changes the texture enough that some cats lose interest. It also protects the surface underneath while you work on redirection.
Deterrents That Don’t Work
Citrus Spray
The internet loves this one. Spray lemon juice or orange peel on your furniture and your cat will avoid it. In practice, the scent fades within hours, and many cats couldn’t care less about citrus anyway. It also doesn’t redirect the behaviour — even if your cat avoids one spot, they’ll just scratch somewhere else.
Shouting or Clapping
Startles the cat temporarily but doesn’t change the underlying need to scratch. They’ll wait until you’re not looking and scratch the same spot. All you’ve taught them is to scratch when you’re out of the room.
Commercial “Anti-Scratch” Sprays
Most contain bitter agents or scents designed to repel cats. Results are inconsistent at best. Some cats ignore them entirely. At £8-12 per bottle, it’s money better spent on a good scratching post.
Declawing
Illegal in the UK under the Animal Welfare Act 2006, and for good reason. Declawing (onychectomy) involves amputating the last bone of each toe. It’s painful, causes long-term complications, and fundamentally alters how a cat walks, jumps, and defends itself. Never consider this. If someone suggests it, they don’t understand cat welfare.
Protecting Furniture While You Retrain
While you’re working on redirection, protect your furniture from further damage.
Furniture Corner Guards
Clear plastic guards that stick to sofa arms and corners. Brands like PROTECTO (about £12 for a pack of 8 from Amazon) are unobtrusive and effective. They don’t deter the cat, but they take the damage instead of the fabric.
Throw Blankets
A thick throw over the targeted area changes the surface texture and protects the upholstery underneath. Tuck it in so it doesn’t slide.
Repairing Existing Damage
For fabric sofas: a fabric repair kit (about £8-12 from Amazon) can patch small areas. For leather: a leather filler and dye kit (about £15-20) can hide scratch marks surprisingly well. Repair after the behaviour is redirected, not before — there’s no point fixing it while the cat is still targeting the spot.
Nail Trimming and Nail Caps
Regular Nail Trimming
Trimming the sharp tips of your cat’s claws every 2-3 weeks reduces the damage they can do to furniture. It doesn’t stop scratching (the behaviour is about more than just the claws), but it makes each scratch less destructive.
Use proper cat nail clippers (about £5-8 from Pets at Home). Only cut the transparent tip — never cut into the pink quick. If you’re unsure, ask your vet to demonstrate the first time. Our healthy treat guide is useful for making nail-trimming sessions more positive.
Nail Caps (Soft Paws)
Soft rubber caps that glue over each claw. They last 4-6 weeks before falling off naturally as the claw grows. Effective at preventing furniture damage, but many cats dislike the application process, and they prevent normal scratching behaviour (which cats need for claw maintenance and stretching). Use them as a short-term measure while retraining, not a permanent solution.
When Scratching Might Be a Bigger Problem
Occasionally, excessive or sudden changes in scratching behaviour indicate something beyond normal territory marking.
Stress or Anxiety
A cat that starts scratching more — especially in new locations — may be stressed. Common triggers:
- New pet or baby in the household
- House move
- Change in routine
- Conflict with other cats (indoor or outdoor)
- Building work or loud neighbours
If you suspect stress, address the underlying cause. The International Cat Care resource has excellent guidance on feline stress indicators. A Feliway diffuser (about £20-25 from Pets at Home) can help in the interim — it releases synthetic feline pheromones that many cats find calming.
Medical Issues
Cats with overgrown claws, arthritis, or paw injuries may scratch differently or more frequently. If your cat’s scratching pattern changes suddenly, a vet check is worth it.
Multi-Cat Households
In homes with more than one cat, scratching increases because territorial marking becomes more important. Each cat needs their own scratching surfaces in their own territories — don’t expect two cats to share one post in a communal area.
Frequently Asked Questions
My cat only scratches when I’m not home. What do I do? This is common and often indicates boredom or mild separation anxiety. Make sure your cat has enough stimulation while you’re out — window perches, puzzle feeders, and interactive toys. Place scratching posts near windows and doors where they spend time alone. A camera can help you identify exactly when and where the scratching happens.
Will getting a kitten be easier than retraining an adult cat? Kittens are easier to train initially because they haven’t developed furniture-scratching habits yet. But all cats need appropriate scratching surfaces from day one. Start a kitten with a small, stable post and upgrade as they grow.
My cat scratches the carpet, not the furniture. Is the solution different? Same principles, different orientation. Cats who scratch carpets often prefer horizontal scratching surfaces. Get a flat cardboard scratcher or a sisal mat and place it over the carpet spot they’re targeting. Horizontal scratchers are cheaper and widely available.
Does catnip on the scratching post really work? For the roughly 70% of cats that respond to catnip, yes — it creates a strong positive association with the post. Rub dried catnip directly into the sisal or sprinkle it on a cardboard scratcher. Refresh weekly as the scent fades. The remaining 30% of cats are genetically unresponsive to catnip; try silvervine instead.
How many scratching posts do I need? At minimum, one per cat plus one extra — the same rule as litter trays. Place them in different locations around your home, especially near furniture that’s been targeted and near sleeping spots.
