Well... I was reading up on swine breeds the other day and stumbled upon this:
"Most people who purchase these pigs want them as pets, but these pigs do not necessarily stay small, cute, or cuddly. As stated above, their average weight is close to 100 lb., and they do not like to be picked up or held. Unlike cats and dogs, pigs are prey not predators, so being lifted up or restrained causes them extreme alarm. "
