Haha! Britain's "Horsegate" scandal is what inspired this thread in the first place. At first I was horrified, but after some consideration, I began to question if it was really that big a deal.
To my knowledge I've never eaten horse, but I would do so in a pinch. Same goes for dog and cat.
Meat is nutrition.
Of course, I'd like to think I'd draw the line at cannibalism.
