Miss Kitty has learned to use her scratching post to keep her nails trimmed.
There are two scratching posts in the living room which have been sprayed with cat nip but the chair and couch are ripped to pieces. Plus, they have the whole outdoors.
If one either plans on having dogs and cats in the same house or expects to have his or er cats get out once in a while, the kitties better keep their claws and the kittie parents need to get scratchers for the kitties to work on.
