I have a few of those around her somewhere.. I picked them up on clearance.. a ball you hang from a tree and it suppose to call in critters to your trap... So I know people use a feather in the wind on a string to call in bobcat.. So those small calling devices might work? Of course they could cause your critter device to be stolen and your trap too... just a post to make you think of things you don't ever think about...
