Why Does My Cat Scratch the Furniture?
Scratching is a natural, essential cat behaviour - not spite. Cats scratch to maintain their claws, stretch their muscles, and mark territory with scent and visible marks. The goal is to redirect it, not stop it.
Why cats must scratch
Scratching is a healthy, instinctive need, not naughtiness. It removes the worn outer layer of the claws to keep them sharp, gives a deep, satisfying stretch through the shoulders and back, and leaves both a visible mark and a scent (from glands in the paws) that says “this is mine”. A cat that scratches your sofa is doing something completely natural - just in the wrong place.
Why they choose the sofa
Cats prefer to scratch sturdy, textured surfaces in prominent locations - exactly what your sofa, carpet or door frame offer. They often scratch near where they sleep or at the edges of their territory, and after waking up. If the only appealing scratching surfaces in the home are your furniture, that is what they will use.
Give them a better option
The solution is to provide scratching posts and pads that genuinely compete with the furniture: tall and sturdy enough for a full stretch (a wobbly post gets ignored), in materials cats love like sisal rope, cardboard or carpet, and placed where your cat already wants to scratch - next to the sofa, not hidden in a back room. Offer both vertical posts and horizontal pads, since cats have preferences.
Protecting your furniture
Make the furniture less appealing while making the post more appealing: temporarily cover targeted spots with double-sided tape or foil, rub catnip on the new post, and reward your cat for using it. Keep claws trimmed, and consider soft nail caps if needed. Never punish scratching - it is a need they cannot suppress, and punishment only creates stress.

Scratching is maintenance, not vandalism
A cat scratching your sofa is not expressing an opinion about your furniture. Scratching does several jobs at once: it removes the worn outer layer of the claw, it stretches the whole back and shoulder chain, and it leaves both a visible mark and a scent signal from glands in the paws. That last part is why the location is never random and why cats return to the same spot.
This matters because it rules out the two responses people reach for first. You cannot stop a cat scratching, because it is a physical need rather than a habit, and you cannot reason him out of the location, because the location is the message. What you can do is make a better option available and make the current one dull.
Read the spot he has chosen
Look at where he scratches and you will learn what he wants. Height tells you whether he is stretching upwards or working horizontally - some cats are vertical scratchers and some are emphatically not, and buying the wrong orientation is the single most common reason a scratching post is ignored. Texture tells you what his claws want to catch on. Position tells you the rest: cats scratch near where they sleep, at doorways, and at the boundaries of their territory, which is why the arm of the sofa nearest the door is so often the casualty.
The sofa usually wins on all three counts at once. It is tall, it is firm enough to pull against, it is covered in a material that shreds satisfyingly, and it is in the middle of everything. Most cheap scratching posts lose on every count, which is not the cat’s fault.
What a post has to do to be chosen
It has to be tall enough that he can extend fully - a cat at full stretch is longer than most posts are high. It has to be heavy or well anchored, because anything that wobbles under load gets abandoned immediately and permanently. It has to offer the orientation he actually uses, which you now know from watching. And it has to be in the right place, which means beside the thing he currently scratches, not tidied away in a spare room.
Put it exactly where the problem is. You can move it later, a few inches at a time, once the habit has transferred. Most people put the post where they would like it to live and conclude that their cat is stubborn.
Making the sofa less appealing
Cover the target temporarily with something that does not reward the claws - a throw, a tucked sheet, anything that removes the satisfying catch. The point is not to punish but to make the alternative obviously better while the new habit forms. Cats commit to a location quickly once it works, and the temporary measures usually come off within a few weeks.
Reward the right choice when you see it. A cat who uses the post and is quietly praised or fed for it is being told he chose correctly. And keep claws in reasonable condition through use rather than intervention - if you think trimming is needed, that is a conversation with your vet or a groomer who can show you in person, not something to attempt from a written description.
What never works
Shouting, spraying water and punishing after the fact all fail, and they fail in a specific way: they do not stop the scratching, they teach the cat to do it when you are absent, and they damage his sense of you as safe. A cat cannot connect your reaction to a behaviour he considers entirely reasonable.
Declawing is not a solution - it is the amputation of the last bone of each toe, it is illegal in many countries, and it causes lasting pain and behavioural problems. If anyone offers it as an option, the answer is a different vet.
Be careful, too, with deterrent sprays and scented products. Cats process substances differently from dogs and people, and a number of things marketed as natural are genuinely unsafe around them. Anything you are considering applying near where your cat sleeps, walks or grooms is worth asking your vet about first - the reasoning is set out in the first aid page.
When scratching means something else
A sudden increase, or scratching in new places, can be about stress rather than claws - a new animal, a new person, building work, a change in the household, or something visible through a window. Scent-marking increases when a cat feels his territory is uncertain, and more scratching is one of the ways that shows.
Excessive attention to the paws themselves, limping, bleeding, or a cat who seems sore is a different matter and needs a vet rather than a new post. Same for any abrupt behavioural change in an older cat. Go in with specifics: when it started, where, how often, what changed at home. The two-minute preparation covers making that appointment count, and the triage helper will tell you whether it needs to be today. For a cat still settling in, the first thirty days with a kitten is where these habits are cheapest to establish, and pet-proofing your home covers what else is within reach of a cat looking for something to do. If a stressed cat has also started chewing on plants, several common houseplants are a real hazard and worth checking.
Most quirks are perfectly normal. If a behaviour changes suddenly or comes with other signs of illness, check with your vet. Full disclaimer.
