There isn't a difference when they evolved from ordinary humans. @WilsonCare to explain what that electronic nudge leash thing is? Also, you know that's gonna piss it off right. It isn't a herd-able creature and will think you're provoking it

Essentially a kind of ring. Unless the creature is sentient, it will stay in a certain radius of where the tool is pointed. If it's pointed directly at the creature, then the creature won't have any discomfort. If it moves a certain distance away from the place where the 'leash' is pointed, out of its radius, then it'll begin giving small amounts of pain and a brain-nudge, or essentially just trying to implant a must-go-back instinct. Not really painful, but aggravating.
