I searched for days online, including this website for the right type of cat tree for me.  I made a great purchase.  I put it together with my 14 yr old niece, it was a piece of cake!  My cat is was crazy before...She was all over the furniture, crawling up decorative trees... anyway now she has an awesome play area!  She plays all over this thing. Now my cat is rather small, still less than a year old and she sleeps comfortably in the box house, with a small blanket.  I really made this purchase for the hammock and heighth, unfortunately she does not use the hammock.  Overall, for the price, it was worth every penny spent!!
