Question: is there any such thing as a mini pig

Answer: Yes, Miniature pig (also micro-pig, teacup pig, etc.) is an erroneous term that is used to refer to small breeds of domestic pig, such as Pot-bellied pigs, Göttingen minipigs, Juliana pigs, Choctaw Hogs, or Kunekune (and specimens derived by cross-breeding with these). Notable features of most miniature pigs distinguishing them from other pigs may be defined by their possession of small, perked-back ears, a potbelly, sway back, chubby figure, rounded head, short snout, legs, and neck, and a short tail with thick hair at the end. Typically, most breeds of mini pigs will range from the minimum weight of 50 pounds (23 kg) to 200 pounds (91 kg).
