It took a few days, but kitty finally went into the little house and took a long nap.  She has decided that this is a good place to hide out, but I can't get her to use the scratching posts or to climb up to the perches.  She just doesn't know what to make of the whole thing yet.  

Good value for the price, and the tree seems to be very well-built.  I wish the perches and the hide-out house were a little larger, otherwise it would have received 5 stars.
