I've adopted 5 kitties this year, we needed a larger and sturdier play unit.  They love it!  There is enough room on it for all kitties at one time.  I did take the ball and string off because Mystic would sit above it, lean down, and play.  She got her nail stuck in the string and tried to jump down.  She was ok, but I cut the string off that day!!  Yes I would recommend it!
