I'm making an eroguro inspired rpg game where a bunch of teens have animal like abilities. I have an idea for one kid who has a pet vulture and eats corpses, but I would like to explain that in a smart way, so can someone help? I could just say "oh it's just a game" but I want a better explanation. can a person survive by eating mainly corpses? how can vultures eat carcasses, and could a human develop something similar?
