These tiny piglets were born and raised at Pennywell Farm in Buckfastleigh, England. Micro or miniature pigs grow to just 14 inches long, and weigh only 9 ounces when they are born. At two years old, they are fully grown and weigh between 40-65 pounds and are around knee height at 12-16 inches tall. Micro pigs can live for up to 18 years, and make popular pets as they are low maintenance, quiet and surprisingly clean. (Photo by Richard Austin/AP Photo/Rex Features)
