We bought this to entertain our cats.  As usual, they use it intermittently.  But they do seem to enjoy it when I put cat nip on it.  They like scratching the posts and hanging out on the different levels.  The do not, however, hang out in the sleeping areas.  And I think they are suspect of jumping to the highest levels (esp our bigger cat)  because the tree shakes.

Overall, though, the tree is fun and does entertain our cats!
