I can't believe this tangent actually led to me typing bestiality into any sort of box on the Internet, but according to dictionary.com, he actually used the word correctly. A better term for it would of course be much preferred.
I believe I've made part of this suggestion myself before (with more space-effective carts and such only pullable by teams of animals), so it'd be wrong to disagree with it. Animal taming is actually fairly high on the list of 'things I'd like to see'.
