Teacup pigs, also known as miniature pigs or micro pigs, are small domesticated pigs that are bred to be much smaller than standard farm pigs. They typically weigh between 20 to 100 pounds when fully grown, depending on their genetics and diet. These pigs are often marketed as pets due to their cute appearance and playful nature. Despite their small size, teacup pigs require proper care, including a balanced diet and regular veterinary check-ups. They can live for 12 to 20 years, making them a long-term commitment for potential owners. It's important to research and understand their needs before bringing one into your home.
