They did. A goat could not physicaslly hold on like that. My brother spent 6 months living in western Africa and that's something done commonly down there when carrying an animal back home for butchering.
I don't know why they think that they can treat the animals they eat worse then the ones we don't. They should be treated just as well, or at least better then they are. I mean, they do feed us after all, pay some respect.
