Our kitty fortunately doesn't scratch much. We do have a nice 30" tall sisal post that she loves scratching on. Lately I have been trimming all of her claws a bit because she kept getting herself hung up on the carpet (or my precious Ibex!!! Nooo!!! ) and this has really been helping with the problems that her long sharp claws pose. She does really like to scratch often on her post after trimming, though, so I'm not sure that trimming by itself would help with a cat that likes clawing.
