Quick answer: Cover the corner they already attack, put a sturdy sisal scratcher flush at that arm, and reward every scratch on the mat for 2–4 weeks. Punishment doesn't work — redirection does.
Why cats pick the sofa
Sofas sit in high-traffic rooms, smell like you, and have soft fabric that feels great under claws. The corner of the arm is the perfect vertical post.
A plan that actually sticks
- Block the old spot — temporary cover (foil, throw, double-sided tape) on the exact corner for 2–4 weeks.
- Offer a better surface — natural sisal at the same height (±1 inch of the arm).
- Reward — treat or play the second they scratch the mat.
- Keep the sofa usable — a side-table scratcher protects the arm and gives you a place for coffee or a lamp.
