I think the more likely and horrifying explanation is they work on heart rate, seeing as they don't seem to penetrate the skin, but instead are just stuck on real tight. That would mean that any time a predator gets excited, upset, angry or even does moderate cardiovascular activity, they get a shock.
Think about that. want to beat off? buzz buzz motherfucker. Late for work? that'll be two zaps; one for the panic of realising you're late and another when you start running to catch the bus. Watching a horror movie? hope you enjoy two hundred volts every time something scary happens.
