A cat's need to scratch is instinctive. It helps them to sharpen and remove the dead outer layer of their claws, stretch and flex their bodies and work off energy. The Catit Style Patterned Cat Scratcher with catnip provides your cat with a corrugated scratching surface, while helping to protect your furniture from claw damage. Catnip included and can be refilled with any Catit Catnip product
