We had a young man recently install some flooring for us. When our pooch was really attracted to him the guy advised that he has quite a menagerie of pets at home. He then added that his very favourite "pet" is a pot bellied pig which he says is both affectionate and highly intelligent. Further he stated that the waste from this pig helps to fertilize his garden. I remember reading some time ago that these pigs have been quite popular with a number of different celebrities worldwide it seems.
