We have our one cat declawed years ago and she has had no bad effects. It is great to not have your furniture tore up. She was not one to use the numerous scratching posts and everything else bought for her so off with her claws! I have a new kitten that will be declawed when she is old enough whether she shows signs of tearing up furniture or not. Right now she is tearing up the declawed cat in playtime and poor Nala doesn't know what to think of those nasty sharp claws that Kate still has! I personally don't care what others think. My cat, my house, my furniture, and my decision!
