Just to piss off the people who want to tell others what they can and cannot eat, I'm going out of my way on my next trip abroad to eat some dog, some cat, and some horse. Who knows, I might even find that I like them.
I prefer the civilized and asthetic nature of an American culture that values these animals as having a higher purpose than food when in our care. This is an optional limitation to place on ourselves, I know, but one I am happy to have. Those places you speak of certainly aren't better than us in any other way, I prefer our sensibilities on the subject of eating pet animals too.
