This cat tree is nice to look at but if you have very active cats like I do it is not quite up to the task.  The bottom circle perch is very wobbly as is the entire cat tree.  It is not very easy for them to jump up on they actually use my lazy boy recliner for a take off and landing site.  The upper box does get used but outside on the ledge it is not very wide.  You definitely have to anchor the tree to the wall.  If you don't I think it would not last but a few month.  All in all not bad but I wish that had bought a square one.  This one just not right for my three bruisers!
