Why does my cat scratch the couch?

2 min read Updated on October 6, 2026

In shortScratching is a need, not misbehavior. Your cat maintains his claws, stretches his whole back, and above all marks: visually, with the traces, and by scent from the glands in his paw pads. He picks the couch because it is stable, at the right height, well placed in the room and smells of you. The goal is not to stop him scratching, it is to give him better in the same spot.

What it often means

Marking: the couch is at the center of the territory and carries your scent. He leaves his.
Maintenance: he removes the worn sheath from his claws.
Stretching: a big stretch of the back and shoulders, often on waking.
Sometimes stress: more scratching near doors and windows when an unknown cat prowls outside.

Signals to read at the same time

Where he scratches: near entrances and passages is marking; near his bed, stretching.
Height and orientation: vertical on the armrest, horizontal on the seat. His post must copy that.
The moment: on waking, when you come home, when a cat passes outside.
Frequency: a sudden spike suggests stress or a change.

What you can do

Put a scratching post right next to the couch, not in a corner: tall (over 3 feet), heavy, stable, sisal or cardboard depending on what he scratches.
Make the couch less attractive for a few weeks: plastic film, double-sided tape, a blanket, with the post in front.
Reward every scratch on the post, and rub it with catnip at first.
Never punish: he will scratch when you are not there, and you will damage the relationship. Trim claw tips every two weeks.

When to see a vet

Scratching is normal. A cat who stops scratching altogether, however, may suffer from arthritis. And declawing, still practiced in some places, is a painful amputation with lasting behavioral consequences: it is not a solution.

Frequently asked questions

He has a scratching post but still scratches the couch. Why?

Often because the post is in a corner, too short or wobbly. The post must be where he already scratches, taller than him stretched out, and must not move. Move it next to the couch and watch.

Do repellent sprays work?

Little and not for long. Making the surface unpleasant to the touch (plastic film, double-sided tape) works better, provided a good post is available right next to it.

Does he scratch to annoy me or get revenge?

No, revenge does not exist in cats. He scratches to mark, stretch and maintain his claws, and he picks the best spot available. The couch is, until the post is better.

Mimo reads behavior. It does not replace a vet.
