is there a such thing as teacup pigs
Miniature pig A miniature pig (also mini pig) is a class of pig developed and used for medical research or as a pet. Miniature pigs weigh between 22.5 kilograms (50 lb) and over 68 kilograms (150 lb) when fully grown. 'Mini pig' has become an acceptable, if imprecise, term that is used to distinguish the difference between large pigs and smaller breeds such as Juliana pigs, Pot-bellied pigs, Choctaw Hog, Kunekune (and specimens derived by cross breeding with these). There are no breeds called teacup, micro, micro mini. These are all adjectives and not breeds of pigs.[1]
Guinea pig The guinea pig or domestic guinea pig (Cavia porcellus), also known as domestic cavy or simply cavy, is a species of rodent belonging to the family Caviidae and the genus Cavia. Despite their common name, these animals are not in the pig family Suidae, nor do they come from Guinea in Africa; they originated in the Andes of South America and studies based on biochemistry and hybridization suggest they are domestic, not wild, descendants of a closely related species of cavy such as C. tschudii.[1][2]
