The two perches on this 48.5-in tower are 16.5-in square with walls standing 7.5-in high, so a cat settles down inside a rim rather than on a flat pad and gets the enclosed feel of a bed without losing its view of the room. Each layer is rated to 35 lbs, and metal tubes hidden inside the posts keep the structure from flexing. The base is round and enlarged to 23.5-in across. Rabbit fur-like fabric covers the perches and the two 15 by 11.5-in platforms, and those covers pull off for washing.
