Query: Plastic Springs are fantastic

I have a very picky cat when it comes to toys. She absolutely loves these plastic springs! She bats them around for hours. If we throw them she chases after them. And most recently she has started picking them up and carrying them in her mouth to where she wants to play with them. (even a few nights upstairs to where we were sleeping!)After a week or so I do a lap of the house dislodging them from under the applicances, furniture, closet doors she might have knocked them into.
