I purchased this product because I had taken in a seven or eight month old kitten who had been born outside to a feral cat who is often in my back yard.  The kltten was used to climbing a tree in my yard and I wanted her to have something comparable to use in my home.  She absolutely loves this tree.  I love it too because it is sturdy and has so many scratching posts which are saving my furniture.  Most of all, I love it because it was so easy to assemble.  Every piece is labelled so there can be no mistakes and all the needed tools are included.  The diagram is very easy to follow, with step by step instructions.  Believe me, if I can assemble it, anyone can.
