If you are trying to get your cat to stop scratching up the furniture in your home, you may want to buy a scratching post to draw their attention away from your tables, rugs and chairs. Their are a various types of scratching posts and if you have a cat who spends a lot of time outdoors, think about getting a scratching post made from wood, which may resemble the feel of a tree. Though, if your cat is like mine, she much prefers fabric covered items, so you may need to experiment a bit to find out their preference. Good luck.

Someone told me that you can simply use a log, but I can’t vouch for this.
