our two kittens absolutely LOVE their cat tree.  There is so much for them to do.  They love to sleep on it, then play on it, then wrestle on it.  It offers so much for them and yet it fits great in our new home.  Sturdy bottom so that you do not have to be afraid that it will tilt over, which was a concern for me looking at the other cat tree's.  Easy to assemble and easy enough to move around if need be.  I am super glad we got this for our kittens.  I think they are, too.
