Particularly in places where they use dogs and cats as food, it's common place to skin or boil live cats and dogs. It apparently makes them taste better.
I'm not about to make them stop eating animals that we would consider "pet shop" animals, To each culture their own. (hindu people treat cows as sacred, yet you would hate it if they tried to force us not to eat them.) BUT, that said, The animals anyone eats should be humanely killed. All animals killed for any reason should be killed in a humane manner, and treated well during their lives.
I'm sarcastic a lot. If I offended you I probably didn't mean to. Probably.
