Mini-pigs that interact with and receive positive feedback from humans during the first two months of life are social and enjoy being with people. They typically have a daily routine that involves eating, drinking, eliminating, socializing, sleeping, and digging. Pigs are very intelligent and need environmental enrichment, or they can become bored and destructive. Pet pigs that are not provided with appropriate environmental enrichment or are not socialized early in life may develop stereotypical behaviors including pacing, staring, excessive drinking, hitting walls, drooling, rubbing on things excessively, and repeated licking or chewing on objects, especially metal and rope. Ideally, pigs should be allowed to root outside in untreated lawn. If they are not allowed access to an area for rooting, they may dig up floors, carpeting, or walls in your home, and chew up house plants. Pet pigs can suddenly become aggressive in response to changes within a household including a change in caretaker schedule, introduction of new pets and people, and discomfort from illness.
