The cat tree is beautiful, looks very modern, & the price was extremely reasonable.  However, my cats have had a hard time using it.  The issue is that the metal bars upon which the respective levels attach is rather obstructive.  When cats jump from one level to the next, this bar makes it somewhat difficult to do so.  My younger more ambitious cats are able to work around it, but the slightly more timid or older kitties consider it too much of a deterrent to use.  Also, the top of the cubby box is slippery, so my cats have a difficult time jumping from the second level to the third tier.  We've had the tree up for over a week, & it's gotten only very minimal use.  We're going to try and affix something to the top of the cubby with a little more traction, so maybe that will help.  The tree looks beautiful; I just wish my kitties were more interested in using it.
