Rubber wood forms the frame of this 48.5-inch tower, with thickened boards and rounded edges that hold up to daily jumping. A cushioned top perch measuring 15.5 by 15.5 by 3 inches sits at the highest point for watching the room, and below it a jumping platform and two padded resting zones spread the climb across the height. The condo has three entry holes, one round at 7.5 inches and two square at 7.5 by 7.5 inches, so a cat can duck in from whichever side it approaches. Each layer takes 33 lbs. Sisal wraps the posts for scratching. A 23.5 by 15.5 inch base, anti-slip foot pads and an included anti-toppling strap keep the 37.5 lb tower steady even when a cat lands hard on the top perch.
