The sisal carpets on this 56-in cat tower lift off, so the surface a cat destroys first can be swapped instead of retiring the whole tower. Two condos sit at opposite ends of the frame: the upper one is open on four sides for airflow and a view across the room, while the curved lower house closes in felt for a cat that wants dark. Both run about 14-in wide with an 8-in entry. Solid plywood decks ride on metal support posts in a simulated wood grain finish, each level carries 22 lbs, and the 24 by 16-in base holds the 34-lb frame.
