This self-groomer provides your cat with a constant source for rubbing and scratching, which helps to keep your home clean and hair-free. The soft bristles massage the skin, and remove loose hair at the same time. The groomer attaches to walls, corners or any flat surface using the double-sided adhesive strips included, or with screws (also included) for a more permanent placement. The catnip can be added inside the groomer to attract the cat. Reusable design removes easily. Hand wash. Plastic. 3 1/4"L x 2"W x 5"H.
