If you are interested in adding a bit of an exotic pet to your home, a pig might be just the answer. Pot-bellied pigs are charming, intelligent, and affectionate companions. With the proper training and maintenance, they make great pets. Because potbellied pigs are very social animals, they are much happier pets if they have a pig companion. In fact, they are far less likely to become aggressive if there’s another pig in the household. Pot-bellied pigs typically live for 14-21 years, with an average of 15-18 years. To reach maximum lifespan, they must be fed a nutritionally complete diet and receive proper medical care. Pigs are very clean animals. They do not have a body odor and like a tidy space to sleep in.
