I really like this perch.  It is just the right size to place in front of a window.  I would have given it 5 stars but there are 2 problems with it.  First, I have to put a chair next to it for my cat to use to get to the top perch.  Otherwise, my cat can't get to the top.  Second, there is a very large cut out on the top perch.  I have a large cat and she couldn't lay on it comfortably facing the window.  I cut a piece of plywood and covered it with carpeting and placed it in the top perch.  Now, It doesn't have the cutout anymore, and my cat fits perfectly.
