Great product, great price, great quality, and fast delivery.  I have 2 adult cats and they both love it.  We had a cat bed that we put on one of the lower shelves and they sleep in there all the time.  They also like the top platforms to sit and watch out the window.  It is sturdy and able to handle both adult cats. One of our cats is declawed and the other is not and they both love to scratch the posts.  The house could be a little bigger but they still sleep or sit in the house and watch what is going on below them.  It has really brought the cats out more and we really enjoy them!  I'm so happy we made this purchase.  Both cats really enjoy it! It was definitely worth every penny!
