If we talk or write about cavies we biological correctly mean the domestic rodent guinea pig Cavia Porcellus a subspecies of Cavia. It is not really clear when and why this animals were domesticated by humans and due to its small body it is very difficult to get any archaeological founds or data. There are various and diametrical evaluations but it seems that Guinea Pigs are domesticated many thousand years ago in South America for joy and of course for food and to get the pelt for clothing.

Guinea pigs are known in Europe for some hundred years. There are several evaluations too how they came to Europe. In german Guinea Pigs are called “Meerschweinchen” (“Sea-Pigs” – not to confound with the sea cucumbers). There is a theory that this name is based from spanish sailors who brought it from South-America to Europe over the sea.
