This is what I find. One or more cats has decided that using a piece of furniture makes a great cat scratching post. I keep a blanket on the back of the chair and small sofa in the family room to help keep it in nice condition. A lot of good that has done!
It's a good thing I love them all otherwise they would know how it feels to live out of doors!!! Not that I would do that, but the thought did cross my mind briefly. :)
