In all seriousness... this is an area you'd want to avoid. Even though the bits wouldn't strictly speakign be carved from a human, and thus it wouldn't *exactly* be canibalism... you wouldn't want to give some chimera-bacon to someone, have them say, "Hey! This tastes a little different... but it's *really* *good*! Where can I get more?"
Where will the chimera-pigs live...seperate housing from non-chimera? How would someone know the difference, would they have to ask prior to eating?
