Buy some double sided stickey tape. Stick it where she scratches. She won't do it again. They -hate- how it feels. My first kitten tried to scratch my boyfriends couch so his mom put like 2 strips of double sided tape down. He put his paw on it once and he's never tried it again. On their couchs or mine or any other piece of furniture. Works a treat and its really cheap.
