Scratching is the cats natural method of shedding the outer nail layer of their claws, helping to maintain healthy claws and paws. The OurPets Alpine Climb Incline Cat Scratcher provides cats with a premium corrugate surface which grooms your cats nails. Cats appreciate the tight nooks and crannies that the corrugate provides which helps them keep their nails healthy. The scratcher is at an ideal scratching angle and is reversible for double the scratching life. Pet Zone premium North-American-grown catnip is also included. Some easy assembly is required.
