I recently lost both of my adult cats and wound up getting a kitten (not my first choice as I like the adults better). I forgot how active kittens are and we just couldn't keep up with her activity level. I purchased this thing and she is happy, happy, happy all the time. Watching her on this thing is like having a fish tank for me. She is complete entertainment and keeps herself busy got long periods of time. I do recommend this for cats with claws though because I also bought one for my parents cats and they don't really know what to do with it because they don't have the nails to pull themselves around or to climb up and down it. Mom says they only use the one level that even with their counter and that's kind of a pity.
