Scratching is the cat’s natural method of shedding the outer nail layer of their claws, helping to maintain healthy claws and paws. The OurPets Multi-Surface Incline Cat Scratcher provides cats with premium corrugate and carpet surfaces which groom their nails. Cats appreciate the tight nooks and crannies that the corrugate and carpet provide which helps them keep their nails healthy. The scratcher can be set to multiple ideal scratching angles.
