Count me as another high-five for not de-clawing your cat! Years ago I had an acquaintance who de-clawed her kitten's front feet, and that poor kitten walked only on his hind legs for months. Broke my heart every time I saw him. The owner thought it was funny.
I have a friend who has 5 acres and several rescued cats, both indoor and outdoor. She gave me very good advice - do NOT buy carpet-covered scratching posts! It only teaches them that it's okay to scratch carpet. Get the sisal rope covered posts, or bark like a previous poster. I think those materials are healthier for the cats anyway.
