Query: Kitty didn't care for them

After reading all the rave reviews, I purchased this product, only to discover that my 4-month old kitten did not care for it at all. I tried to get him to play with the springs by bouncing them around and flicking them across the hardwood floor. He chased after them out of curiosity, but promptly stopped when they stopped moving. He does love to play with little furry mice though. He can bat those things around for hours. Oh, and don't even get me started on Da Bird. That thing is like kitty heroin.Only your kitty can tell you what he likes...unfortunately, these missed the mark. Also, I don't know if this is an issue for the cats that do like this toy, but the edges of the springs seem a little sharp.
