After reading all of the wonderful reviews on this cat tree, I decided to order it for my new kitten and my 12 year old cat. They were already checking it out as I was putting it together. Very simple to assemble and it arrived in a couple of days. My cats love it and so do I! The little pompoms lasted less then 5 minutes and I didn't even get a chance to hang them, so I hung one of their favorite toys in place of the pompoms. Misty and Kelsey are very happy kitties now.
