Why Does My Cat Scratch the Sofa? Causes and the Best Solutions

August 04 2026, by Michael van Wassem, 8 min reading time

Your cat isn't scratching out of spite: it's claw care, territory marking and stretching all in one. Here's how to redirect the behaviour to a scratching post instead of the sofa.

The short answer: cats don't scratch to ruin your sofa — they do it to maintain their claws, stretch their muscles and spine, and mark their territory with the scent glands in their paws. They choose the sofa because it's sturdy, tall enough and usually sits in a central spot in the home — exactly where a good scratching post should be too. Put a sturdy, tall scratching post in that spot and reward your cat for using it, and most cats switch over on their own within a few weeks.

Almost every cat owner runs into this sooner or later: fresh snags in the sofa arm, frayed wallpaper, or scratches in a wooden table leg. It's one of the most common sources of friction between cats and their owners — and also one of the most avoidable, with the right approach. In this article you'll learn why cats scratch, why they sometimes prefer the sofa over a scratching post, how to choose a post your cat will actually use, and what not to do.

Why do cats scratch in the first place?

Scratching isn't naughty behaviour — it's an instinctive act that serves several purposes for a cat at once:

• Claw maintenance. Scratching removes the old, outer layer of the claw (the claw sheath), revealing a sharp new layer underneath.
• Territory marking. Cats have scent glands in their paw pads. Scratching leaves not just visible marks but also a scent signal that gives other cats — and the cat itself — a familiar, "safe" feeling.
• Stretching and activating muscles. While scratching, a cat fully stretches its back, shoulders and front legs — similar to how we stretch first thing in the morning.

Because scratching is such a fundamental need, you can't train it away. What you can do is teach your cat to scratch in the right place.

Why does your cat choose the sofa over the scratching post?

Usually the reason is surprisingly practical. A cat picks a scratching spot based on sturdiness, height and location — and the sofa often outperforms a scratching post that's tucked away in a corner.

• Sturdiness. A wobbly or lightweight scratching post doesn't offer enough resistance. If the post feels unstable, your cat will look for a surface that actually holds up, like the arm of the sofa.
• Height. Cats want to fully stretch out while scratching. If the post is too low, the back of the sofa is simply more comfortable.
• Location. A scratching post stuck in an out-of-the-way corner or separate room is often ignored. Cats prefer to scratch somewhere visible and central — often near where they sleep, eat, or watch you come in.
• Material and texture. Some cats have a strong preference for a particular texture: sisal, cardboard, fabric or wood. If the post's material doesn't match that preference, your cat will fall back on the sofa's upholstery.

Choosing the right scratching post: a checklist

A scratching post that ticks the following boxes will be accepted by most cats far more readily than a random one off the shelf:

• Sturdy and heavy enough. Push against it yourself: it shouldn't tip over or wobble when your cat leaps at it with force.
• Tall enough to stretch on. Aim for at least 70–90 cm (28–35 inches), so an adult cat can fully stretch while standing on its hind legs.
• Both vertical and horizontal options. Some cats prefer scratching upright, others flat on the ground. A post plus a scratching mat or pad together cover both preferences.
• Natural material such as sisal rope. Sisal offers the firm resistance cats look for and keeps its structure the longest.
• The right spot. Place the post near the sofa, by the room's entrance, or next to a window — not tucked away in a separate room.
• Enough posts for multiple cats. Plan for at least one scratching post per cat, plus one extra, spread across different spots in the home.

A sturdy, multi-level starter option is the Gor Pets Cat Scratcher Charlotte/Pole. For an affordable, quick-to-place addition next to the sofa, a compact sisal scratching post also works well. Take a look at the full range of scratching posts at Fidello for more options.

How to teach your cat to use the scratching post

• Start by placing the post right next to the sofa. Only move it to its permanent spot once your cat is already using it.
• Make the post appealing. A little catnip spray on the post will draw many cats to it naturally.
• Reward use immediately. If your cat scratches the post, give a treat or a stroke right away. Timing matters here: within a few seconds of the desired behaviour.
• Calmly redirect scratching on the sofa. Gently pick your cat up and place them by the post, without startling, punishing, or shouting "no."
• Be consistent. Repetition is key: most cats switch over within two to four weeks, provided the post meets the checklist above.

What you shouldn't do

Declawing (the surgical removal of the claw bones) doesn't solve the problem — it causes lasting pain and can lead to behavioural problems. The procedure is banned or heavily restricted on welfare grounds in a number of countries, except in cases of strict medical necessity. Think of scratching as behaviour to redirect, not to eliminate.

Protecting furniture temporarily during the switch

While your cat is still getting used to the scratching post, you can make the sofa temporarily less appealing:

• Double-sided tape or aluminium foil on the spot your cat scratches most. Most cats dislike this texture under their paws.
• A throw or furniture cover over the favourite scratching spot, until the desired behaviour is learned.
• Citrus scent (such as a piece of peel) near the sofa, since many cats avoid this smell.

Treat these tools as temporary support alongside — not instead of — a good scratching post in the right spot.

When excessive scratching is a warning sign

A healthy cat scratches with some regularity, but a sudden, much more intense or compulsive pattern of scratching can point to underlying stress, boredom, or a lack of mental stimulation — for example after a move, a new pet in the home, or too little playtime. Frayed, torn or inflamed claws can also signal an underlying claw care issue. If you notice the scratching behaviour changing sharply, coinciding with other behavioural changes, or the claws or paws not looking healthy, contact your vet to rule out medical causes.

Common mistakes when redirecting scratching behaviour

• Buying a cheap, wobbly scratching post. If the post isn't sturdy, your cat simply won't use it.
• Placing the post in an out-of-the-way corner. Cats prefer to scratch somewhere visible and central — not tucked away.
• Punishing instead of redirecting. This increases the chance of secretive behaviour and can damage your cat's trust in you.
• Giving up too soon. Switching over takes an average of several weeks of consistent repetition; concluding "it's not working" after just a few days is too quick.
• Only having one scratching post for multiple cats. This often leads to competition or to cats scratching furniture as an alternative.

Frequently asked questions

Does trimming claws help prevent scratching on the sofa?
Short claws reduce the damage but don't remove the need to scratch. Always combine claw trimming with a suitable scratching post in the right spot.

Why does my cat scratch mainly in the morning or right after waking up?
That's completely normal: scratching is part of stretching after a nap, just as cats do after getting up from their bed.

Is it better to buy a scratching post or make one myself?
Either works, as long as the post is sturdy, tall enough, and has a firm, natural texture like sisal. A ready-made post has the advantage that sturdiness and height are already well suited to cats.

My cat does use the scratching post but still scratches the sofa too. What now?
Check whether the post is in the right spot (close to the sofa, not tucked away) and whether it's sturdy, tall, and made of the right material. Often, adding a second post in a different spot, such as right next to the sofa, solves the last part of the problem.

Summary and conclusion

For cats, scratching isn't about naughtiness — it's claw care, marking and stretching all in one, a basic need you can't train away but can redirect. Choose a sturdy, tall scratching post with natural sisal, place it centrally near your cat's favourite scratching spot, and consistently reward the behaviour you want. Punishment backfires, so it's not an option. Get that foundation right, and most cats switch over on their own within a few weeks — leaving the sofa free of fresh scratches.
