Why Cats Scratch Furniture and How to Redirect It

Quick answer
Cats scratch furniture to sharpen claws, mark territory with scent, stretch muscles, and express emotions like excitement or stress. Furniture appeals to them because it is tall, sturdy, and lets them dig in fully. The fix is not to stop scratching but to give your cat a better surface to scratch instead.
Four Reasons Your Cat Scratches in the First Place
Scratching is not misbehavior. It is a set of overlapping biological needs your cat meets every time those claws hit your couch. Cats scratch for four main reasons. They remove the dead outer layer of their nails, leave scent from glands in their paws to mark territory, get a full-body stretch, and release emotions like excitement or stress. The ASPCA adds that cats also scratch to send signals to other cats, either to mark space or as a mild threat display.
Because all of these needs are real and constant, trying to stop scratching entirely will not work. The goal is to redirect it to surfaces you can live with.
Why Furniture Is So Attractive to Cats
Your sofa is not a random target. Cats prefer tall, sturdy objects that let them dig their nails in and get a solid grip, and most furniture fits that description perfectly. Cats are drawn to objects that offer height and stability. Drapes are another common target because they are tall enough to allow a full stretch.
Scent also plays a role. Once a cat has scratched a spot, the visual marks and the scent left behind make that location feel like an established scratching site. That is why the same corner of the couch gets hit again and again.
Choosing a Post That Actually Competes With Your Couch
Most cats prefer a scratching post that is at least 32 inches tall, will not wobble when used, and is covered in sisal rope. A post that tips or shifts when a cat leans into it will be abandoned quickly. Height matters because cats scratch partly to stretch, and a short post does not let them extend fully.
Not every cat wants the same surface or orientation. The ASPCA recommends offering posts made of cardboard, carpeting, wood, sisal, and upholstery to find what your cat prefers. Some cats scratch vertically; others prefer a horizontal surface or a slanted one. Once you identify your cat’s preference, corrugated cardboard and bare wood are also good options if sisal is not a hit.
One practical note: do not throw away a post just because it looks ragged. Cats actually prefer shredded, torn posts. They can really dig their claws into the material, and the familiar scent makes the post more appealing, not less.
Placement and Introduction: Getting Your Cat to Use the Post
Location is as important as the post itself. Place the new post right next to the spot your cat currently scratches. If the target is the couch arm, the post goes beside the couch arm. If it is the wall near the front door, the post goes there. Location matters.
To introduce the post without creating a stress response, use play. Try using a fishing rod toy or laser pointer near the post so the cat interacts with it naturally during play. Rubbing catnip on the post for the first several days also encourages investigation. What you should not do is carry your cat to the post and press their paws against it. Doing this can frighten the cat and cause them to avoid the post entirely, and possibly avoid you as well.
Making Furniture Less Appealing While the Transition Happens
While your cat is learning that the new post is better, you need to make the furniture less satisfying to scratch. One simple approach is to cover the furniture with a tight-fitting sheet, which is far less grippable than sisal. For smaller areas, double-sided sticky tape works well because cats dislike the sticky sensation on their paws.
The ASPCA offers more options to protect furniture. You can try plastic sheeting, sandpaper, or an upside-down vinyl carpet runner placed on the floor where your cat stands to scratch. The knobby side should face up. Once your cat uses the post regularly, you can remove the deterrents from the furniture.
If you catch your cat scratching furniture in the moment, the ASPCA suggests a startling sound like a hand clap or a brief water spritz as a last resort. Use this sparingly, because the cat may associate the unpleasant event with you rather than with the furniture, which can damage trust.
Nail Trimming and Caps as a Damage-Reduction Layer
Redirecting scratching to a post is the primary solution, but two additional tools can reduce damage in the meantime. The ASPCA recommends clipping your cat’s nails regularly, which reduces the sharpness of the claws without removing the cat’s ability to scratch. Plastic nail caps are another option: they attach to the claws with adhesive and last roughly four to six weeks, according to the ASPCA. Caps do not stop the scratching behavior, but they prevent the claws from catching and tearing fabric.
If you are unsure how to trim your cat’s nails safely, a veterinarian or groomer can show you the technique. For more on everyday cat care decisions, the cats topic hub covers a range of related questions.
When a Change in Scratching Behavior Deserves Attention
Scratching is normal, but a sudden increase can be a warning sign. Scratching driven by stress looks the same as scratching for claw care, so context matters. If your cat’s scratching changes sharply with no clear cause, talk to a vet. Do not assume a behavior change is purely behavioral without ruling out a physical cause.

Frequently asked questions
How many scratching posts does a cat need?
The ASPCA recommends providing posts in multiple locations, especially once you identify your cat's preferred surface. A single post in one room may not be enough if your cat scratches in several spots. Place posts near the areas your cat currently targets and add more once you know what surface and orientation your cat prefers.
Can I use a spray bottle to stop my cat from scratching the couch?
The ASPCA lists a water spritz as a last resort, not a first step. Cats may link the unpleasant experience with you rather than with the furniture. Covering the furniture with a sheet or double-sided tape while placing an appealing post nearby is a more reliable approach. It also avoids damaging your bond with your cat.
My cat ignores the scratching post I bought. What should I try next?
Check height, stability, and surface. Most cats want a post at least 32 inches tall that does not wobble, made of sisal. If yours is short or wobbly, try a different post. Also try a different orientation: some cats prefer horizontal scratchers or corrugated cardboard. Rub catnip on the new post and use play to draw your cat toward it naturally.
Is scratching a sign that my cat is stressed?
Scratching can express stress, but it also helps with claw care, scent marking, and stretching. Scratching alone does not confirm stress. Cats scratch to release emotions including both excitement and stress. If your cat's scratching changes suddenly, a vet can help figure out the cause.
Do plastic nail caps hurt cats or stop them from scratching?
According to the ASPCA, plastic nail caps attach with adhesive and last roughly four to six weeks. They reduce damage to furniture but do not stop the scratching behavior itself. They are considered a damage-reduction tool, not a behavioral solution. If applied correctly they should not cause pain, but a veterinarian or groomer can apply the first set to show you the proper technique.
