Why does my cat need a scratcher for healthy claws?

Scratching sheds the worn outer claw sheath, stretches the body, and marks territory — it is maintenance, not mischief.

Cat claws grow in layers, and scratching peels away the dull outer husk to expose the sharp new claw beneath. The behavior also stretches the shoulders and back and leaves scent marks from glands in the paws. A cat without an acceptable scratching post does not stop scratching — it just promotes the sofa.

Choosing a scratcher the cat will actually use

The winning scratcher is sturdy enough not to wobble, tall or long enough for a full-body stretch, and placed where the cat already spends time — next to the sleeping spot or the scratched corner of the couch, not hidden in a hallway. Preference for vertical posts versus horizontal pads differs by individual, so offering one of each answers the question quickly.

Scratching keeps sheaths turning over but does not shorten claws, so indoor cats still need periodic trims. A cat that abruptly stops scratching, favors one paw, or resents having its feet touched may be dealing with claw or joint pain, and that pattern is worth a veterinary consultation rather than a new scratcher.
