I wasn't sure what to expect when getting a huge cat tree for so cheap.  I mainly worried that they would spend more time playing with the box than the actual tree.  I was wrong.  They love it.  The hanging mice are perfect to help stimulate their curiosity.  The platforms are great for naps.  Added bonus: they have stopped using my walls, carpets, couch, chair, etc. as scratching posts.

Pros: Great value, cats love it, multifaceted use.
Cons: Difficult to put together, but that could be attributed to user error and tiny directions.
