I see in my crystal ball that there may be a shortage of family pets in those countries.
Interesting hypothesis, but in Korea, family pets are just as common as here. And they are as loved and wel-cared for as here in USA. There is a distinct seperation of 'pets' and 'food animals' made.
I have eaten dog, and a lot of other 'mystery meat' and can only say one thing - I ate it and have no regrets. It has not lessened my love or appreciation of animals. And if it came down to it; if I died and my animals needed food, heck..Munch away lads!
Its no use to me anymore...lol.
