OK, so the sofa was partially ruined by a toddler and a bottle of purple nail polish but the cat (7.5 months old, neutered) has opened up two seams on the sofa by using it as a scratching post. He has other scratching posts, which he loves, but seems to like variety.
So my question is, what can I do to stop him scratching so much and would a leather sofa fare better or do cats scratch those too? Never had such a scratchy cat before.....
