My cat loves this thing and it looks 1000x better than a traditional cat tree in our living space. We've have had people look twice and say they thought it was a book shelf. It's currently set up against the wall as part of a kitty superhighway in progress. She uses all levels for play and naps. One complaint-- The shelves were jiggling and unstable when in use when I first set it up. I lodged a few rubber disks in the gaps and it solved the problem. It might have been that I messed up the assembly, but this was an easy fix so went with it.
