I bought this in hopes that my kitty cat would love to sit and look out at the outdoors… Ha ha ha the only way I can get him into this is by putting treats into various positions on the cat tree… 
Assembly is relatively easy...The tightening tool was a little difficult to use and would be almost too difficult for a man to use… If they changed the length of the handle it would make it a lot
easier to  use for assembly.  
It is beautiful to look at, and I feel it would be better suited to kittens For it is a little challenging for a bigger cat to have much maneuverability.
