A teacup pig is a small breed of pig that is often marketed as a miniature pet. These pigs typically weigh between 20 to 60 pounds when fully grown, making them much smaller than standard farm pigs. They are known for their playful and intelligent nature, which can make them appealing companions for pet owners. Teacup pigs require special care, including a balanced diet and regular veterinary check-ups. Due to their popularity, some breeders may misrepresent their size, leading to potential issues for owners. It's important for prospective owners to research and understand the responsibilities involved in caring for a pet pig.
