Pigs are very social; they form close ties to one another and are comforted by the close proximity of other pigs. They are extremely intelligent and gregarious, communicating with each other constantly through a complex vocabulary of oinks, grunts and squeals. Most pigs are peaceful and rarely show aggression unless they perceive a threat. Contrary to their reputation, pigs are very clean. Even very young pigs relieve themselves in an area far away from where they lie down and sleep.
