I truly have used a predator against a predator I sealed off my barn once. all but one window. Posted my ladder up so I could reach the hay loft window. from the outside cut me a strip of chicken wire to go over that window. took my staple gun and the piece of wire and ran up the ladder and slapped a few staples into the wire covering the window. then I threw a bobcat I rescued into the barn and shut the doors. when I went to retrap my bobcat there was no animals left in that barn just some feathers. Still to this day have no idea what took place in that 48 hour time frame and dont want to know. I like to call it as the federal game ranger calls a hawk eating your chicken infront of your face. Nature taking its course. the circle of life. LOL
