Three separate condos sit on this 52-in cat tree, the largest measuring 16-in by 15.5-in with a 12-in square entry wide enough for a big cat to walk in rather than squeeze. Metal pipes reinforce the wood frame, and at 66 lb the tree is heavy enough that it does not shift when cats land on the oversized perches. A hole cut through the top perch gives cats a second route up or down instead of one fixed path. Sisal posts and a flat sisal board handle claws, non-slip pads guard the floor, and every cushion pulls off for the washing machine.
