There is no distinction between a mini pig and a micro pig; mini and micro are terms used to describe the same pig. Other names for this animal include nano pig, teacup pig and micro-mini pig.
Miniature pigs typically grow to be between 12 and 14 inches in height and between 20 and 35 pounds in weight. A Juliana pig is another breed of tiny pig, weighing in at between 15 and 30 pounds at maturity.
Miniature pigs are friendlier than larger pigs and enjoy human attention. They are also intelligent and clean animals; they can be trained to use a litter box.
