We are thrilled with our new cat tree!  It looks classy in the corner of our family room.  Our cat Sophie took a few days to trust it until we sprayed catnip spray on it to entice her, then she loved it.  It does sway a little when she jumps up and down to different levels and I think this is what made her a little nervous at first.  But now she is used to it and likes to lay in the cubby hole.  My husband assembled it in about 25 min.  I almost wish we had another cat to see how two would play on it together!  I looked two months for the perfect cat tree for our room space and for everything we thought Sophie would enjoy.  This was the one!
