Size and Color is nice, fits in with most rooms being neutral. I love all the scratching post options for our kitten. She especially loves the hammock and top level. House/Condo level could me much bigger, not much use due to her size, esp with having to screw 2 posts/columns inside to keep together.  Also directions were horrible, be sure if ordering you look at the fact that you need to build from TOP, Down or if not you will have to start all over. This is mentioned in the instructions but in fine print at the bottom.
