Mounted on the wall rather than the floor, this 71-in cat climbing set frees the floor beneath it while giving cats five levels to work through. Four padded platforms stagger in size from 15.5-in by 15-in up to 22-in by 15-in, and a hammock hangs below a cut cat hole so a cat can drop straight into it from the shelf above. A 9-in by 23.5-in sisal mat mounts alongside for clawing. Plywood boards rate each layer to 33 lb, and every plush cushion detaches for the washing machine.
