Our kitty loves this toy.  It's perfectly sized, small enough for her to carry around, but large enough for her to wrestle and kick while rolling around.  Material being eco-friendly and safe was the main reason for the purchase, but it is a great cat toy.  Our kitty plays fetch with this at least few times a day, it has been brought to every room of the house.  I also agree with the previous reviewer about the bell--it's enough to grab kitty's attention but not annoying to human ears while she's playing with it.
