The first step in deterring your cat from scratching is to give him something to play with. The most common types of scratching posts are made of corrugated cardboard and feature a center that rises up slightly. They’re usually over two feet tall and can even be higher. Some scratching posts have sisal coverings, which is a plant fiber that your cat loves to claw on. Other scratchers have rope wrapped around them to encourage them to use their paws.
