Is your precious puss a vertical scratcher? If you answered yes, chances are she likes to sharpen her claws on your sofa, walls, and doors. The catnip-treated Door Hanging Scratchy Pad is designed to entice kitty to do her scratching on a safe and durable carpeted surface instead of on inappropriate vertical areas around the house. This scratching pad can be hung on any doorknob... Just pick the spot your cat likes to sharpen her pretty little claws on most.
