My THREE cats LOVE this!  I found it easy to put together, and all pieces were in the package.  I'm extremely pleased with my purchase, and even more pleased to get this item at a great price.  My cats are all around 9 pounds and with the exception of the circular shelf just below the very top shelf, my cats fit well on the remaining resting spots!  All three cats have found their favorite resting place on their new Cat Tree and thank goodness that each one chose a different spot as their favorite or I may have had to buy another one!
