A transparent capsule sits in the frame of this 44-in cat tree, 12 by 6-in and sized for a cat to curl into, so an animal that likes enclosure still gets light and a view out. The 12-in top perch lifts off and works as a standalone bed on the floor or a sofa, which matters when a cat decides to sleep somewhere else. Four platforms stagger the climb, sisal rope wraps the posts, and matte velvet covers the boards. The base is solid plywood 1.2-in thick, each level carries 22 lbs, and the whole frame weighs 20 lbs.
