My cats have a great interest in this Cat Tree. They love it! They jump and play as if they are young again. It did not take long to arrive. It arrived in one box. All the pieces were packed efficiently. Also, all the parts/screws were in the box. Every piece is marked pertaining to the directions. The directions were clear and concise. Also, it is remarkably sturdy. My cats love all the seating areas on this Cat Tree. They haven't attempted to lay in the hammock, but they were never around a hammock before. I will give them some time. Maybe they will eventually lay in the hammock. I would recommend this cat tree for any cat owners. Finally, the price was extremely low. My cats say Thank You!
