The craze for mini-pigs began in the USA in the late 1980s, when a number of Vietnamese potbellied pigs were imported to American zoos, according the National Geographic. Private breeders then began to inbreed smaller lines to create even more miniature creatures for the pet market.
Rudi, who is barely a year old, will certainly continue to grow. The average miniature-pig normally reaches around 50 cm in height, so its thieves may well eventually have a shock in store.
Rudi's owner is nonetheless determined to have her pet back, and Hit Radio FFH reports that she is offering a €350 reward.
