Mini pigs, also known as teacup pigs or micro pigs, are small domesticated pigs that have gained popularity as pets. They typically weigh between 50 to 150 pounds when fully grown, depending on the breed and diet. Mini pigs are known for their intelligence and can be trained to perform tricks and use a litter box, making them appealing companions. These pigs require special care, including a balanced diet and regular veterinary check-ups, to ensure their health and well-being. Mini pigs can live for 12 to 20 years, so potential owners should be prepared for a long-term commitment. Proper socialization and exercise are also essential for their happiness.
