Easy delivery and easy to construct. 

Our kitten loves this! She plays with the little ball all the time. It took coaching for use the scratching posts but she uses them now. I also just bought some catnip that i plan on rubbing on the scratching posts to further encourage her scratching the posts (instead of the couch).

We wanted this one because it was right at window height so she can look outside when she sits on it and she loves that.
