What makeshift traps can I make in the middle of Iraq to catch a cat that keeps gettng in our garbage. I would set a snare, but I have no trees nearby to tie them to. I can't do a pit trap, because there are Marines that go up and down this area. I was hoping someone could teach me a knot that would only tighten (ala a constrictor knot, but used as a snare) or else some other limited resource ideas.
