if they get hungry enough, they will. Humans behave the same way. When Paris was under siege in the late sixteenth century, the city was starving. When people inside the city ran out of cats and dogs and rats to eat, they began disinterring bodies from the mass graves in the cemetery. They took the bones and ground them into flour to make what became known as Madame de Montpensier’s bread. Bone appetit! (Actually, maybe don’t bone appetit, as many who ate the bone bread died themselves.)
