Micro pigs are much smaller than a standard farm pig and weigh 9oz, about the size of a tea cup when they are born.
At two years old they are fully grown and weigh in around 40-65 lb and are around knee height at 12-16in tall. They can live for up to 18 years, but make popular pets as they are low maintenance, quiet and surprisingly clean.

The piglets are bred in the UK at Little Pig Farm.
Not only do they make great pets, but are the perfect size for whole roast suckling pig. Just kidding.
