1. If they can, pigs form peaceful family groups of ten or fewer members, who sleep in a communal nest. 2. Pigs are more intelligent than dogs, naturally very clean animals, and discriminating eaters. Unable to sweat, they bathe in mud to cool off and to protect their skin from sun and insects. 3. They enjoy novelty and are extremely active and inquisitive. When free to roam, they spend much of their day enthusiastically smelling, nibbling, and manipulating objects with their snouts. A pig's sense of smell is so keen that the animal is trained in France to unearth truffles, an edible fungus that grows underground. 4. Adults in the social group will protect a piglet, leaving food or their own litters to defend the endangered youngster. 5. Touch and bodily contact are especially important. Pigs seek out and enjoy close contact and lie close together when resting. They also enjoy close contact with people familiar to them and will roll over to have their bellies rubbed. 6. They have an elaborate courtship ritual, including a song between males and females. Newborn piglets learn to run to their mother's voice, and the mother pig sings to her young while nursing. After nursing, a piglet will sometimes run to “Mom's” face to rub snouts and grunt. 7. Vivisectors call pigs “horizontal man” because the arrangement of their internal organs is so similar to humans.

Yes indeed, the problem for the unfortunate pigs is that they are really far too similar to us, far too similar for their own good. Perhaps that is why we disparage and ridicule them so much―it puts some metaphorical distance between the two species, without which, our ruthless exploitation of them would be far more distressing for us.
