My cats love this cat tree - I have 3 cats - two of them are really big, and they all love it! I only wish the very top was a little larger because my bigger cats scrunch a little to sit in it, but they still do.  Also wish the pouch that hangs off on the side was a little bigger for them, but like I said, they still do! The circle underneath the top thing is pretty useless... but anyway, this is an awesome cat tree.
