Pet Zone Alpine Climb Incline Scratcher – An angled cardboard scratcher that entices cats to scratch at a natural incline. It’s like a kitty treadmill for scratching: the sloped design and corrugated texture help cats stretch their back and shoulder muscles as they dig in. The scratcher comes with a packet of catnip to sprinkle on, drawing cats to the 6¼-inch deep cardboard surface and away from furniture. And when one side is worn out, you can flip it over to a fresh side, effectively doubling its lifespan for lots of satisfying claw sessions.
