I had ordered on previously for my adult cat and 2 kittens.   They love it exspecially the kittens.  So I had to get one for my daughter as a Christmas Present.  Her cat loves it and sleeps in the hutch!

Very well organized instructions comes with tool you need.  All poles and levels are lettered so you know what goes where!  All small bolts/parts come in plastic and then in a cloth bag so they are not easily lost.

I would Very Highly Reccomend this Tower to everyone!
