At my old farm, the cats would try to hunt or do something to the flocks that would hang out at my tank and field. I never did get to see what they were trying to do, but I'd hear honking outbreaks during night and mornings. Several mornings each season, I'd see groups of cats coming back from areas there were honking outbreaks a few min. before. I would have loved to have seen what those silly fuggers were doing.
