The first thing to understand about cats scratching furniture: it's not bad behavior. Scratching is a need, not a vice. Cats scratch to shed the outer sheath of their claws, to mark territory with scent glands in their paws, to stretch their backs and shoulders, and to relieve stress. A cat who isn't scratching anything has a different problem than a cat who is.

The goal isn't to stop the scratching. The goal is to redirect it.

This matters because most anti-scratching advice — spray bottles, double-sided tape, citrus oils, aluminum foil — focuses on punishing the cat for scratching what you don't want them to scratch. None of these address the actual need. The cat still wants to scratch; it just learns to do it when you're not watching, or when the tape comes off, or somewhere else that isn't great either.

The cats who don't scratch furniture have good places to scratch. That's the entire trick.

What makes a good scratching post

This is where most cat owners go wrong. They buy a scratching post — a small carpeted column on a base — put it in the corner of the room, and find their cat ignoring it for the couch arm anyway. The reason is usually that the post is wrong in one or more specific ways.

It's not tall enough. Cats want to scratch with their full body stretched out vertically. A scratching post that's shorter than the cat's full standing height doesn't let them stretch. Most pet store scratching posts are too short. You want a post that's at least 30 inches tall — taller if your cat is large.

It's not stable. When a cat scratches, they pull. A post that wobbles or tips over fails the test immediately. The cat tried it once, the post moved, the cat won't come back to it. Look for posts with heavy weighted bases, or wall-mounted options.

It's the wrong material. Carpet feels nice to humans, but most cats prefer sisal rope or sisal fabric for scratching — it shreds satisfyingly and matches the texture they like in real bark or wood. Some cats prefer cardboard. Almost no cats prefer carpet, which is why so many carpeted scratching posts get ignored.

It's in the wrong place. Scratching is partly territorial. Cats scratch where they want to mark — usually near where they sleep, near doorways, in central rooms. Putting the scratching post in a back corner means the cat is choosing between marking the post (in an irrelevant location) or marking the couch (in the actual living area). The couch wins.

The fix: get a tall, stable, sisal-covered post (or several), and put one next to whatever your cat is currently scratching. If they're scratching the side of the couch, put the post directly next to that spot. They'll often switch immediately.

When the post isn't enough

Some cats need more than one type of scratching surface. Horizontal scratchers (flat cardboard or sisal pads on the floor) appeal to cats who like to dig their claws downward. Angled scratchers fall in between. Wall-mounted vertical scratchers let cats fully extend.

If you have a serious furniture-scratching problem, try one of each in the rooms where the scratching happens. Cats develop preferences, and you can't predict which one yours will like.

Protecting the furniture while you train

The redirect takes time — anywhere from a few days to a few weeks. During that period, you can make the furniture less appealing without doing anything punishing.

Furniture protectors — clear plastic sheets that stick to the corners and arms of upholstery — work well. They don't hurt the cat or the furniture, but the cat doesn't get the scratching feedback they want, so they move on.

Slipcovers in textured fabrics (not the satin or smooth ones) actually make scratching less satisfying because the texture is wrong from the cat's perspective.

Soft nail caps — small plastic caps that glue over the cat's existing claws — prevent damage without preventing the behavior. They wear off naturally in 4-6 weeks. Not all cats tolerate them, but the ones that do can scratch normally without doing damage. This is much gentler than declawing, which is no longer recommended by most veterinarians.

What not to do

Don't punish the cat. Spray bottles, loud noises, swatting — these don't teach the cat that scratching is bad. They teach the cat that you are scary. The scratching continues; the cat just hides it from you.

Don't declaw. This is amputation, not nail trimming. It's banned in most of Europe and increasingly in US cities. It causes long-term pain, behavioral problems, and changes how the cat walks.

Don't give up after a week. Behavior change takes time. If you've set up good alternatives and the cat is still scratching the couch, the alternatives might not be quite right — try a different material, a different location, a different height — but the basic approach works.

The summary

A tall, stable, sisal scratching post placed next to whatever they're currently scratching. Furniture protectors during the transition. Patience. That's it.

The reason this isn't more common advice is that it doesn't require buying many products — just one or two good ones, placed correctly. Most "how to stop cats from scratching" articles recommend a dozen things because each link earns a commission. We'd rather you solve the problem.
