Title: solid toy
Review: I like these a lot. First off, with even just a little tap, the springs roll on the floor on their own, back and forth, which keeps our kitten's interest and he can play with them for a while on his own without human help. It is tiring running around with him playing with his other toys and these fill in well when the humans need a break! I think they also help to keep him from waking us up to play in the middle of the night. He can play with these on his own.One note: so far, these have only been effective on hard surfaces, so all our springs are in the kitchen and bathroom. Once he bats them onto a carpet they stop moving the way they did and lose their allure.Fun toys!
