At some point in history, humans began to make distinctions between animals they wanted to eat and animals they wanted to tame or befriend. These preferences have evolved to some degree as a result of geographical and cultural boundaries. On grocery-store shelves in Central Asian countries you can find horse meat in a can; in Kentucky horses are highly valued and part of a long racing tradition. In many Western countries we cannot imagine eating the cats and dogs who share our homes, but these animals are meals in other parts of the world. Why do we draw these lines? In doing so, what are we saying about ourselves?
