GuineaPig | The guinea pig (Cavia porcellus), cavy or domestic guinea pig, or cuy for livestock breeds, 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. They originated in the Andes, and earlier studies based on biochemistry and hybridization suggest they are domesticated descendants of a closely related species of cavy such as Cavia aperea, C. fulgida, or C. tschudii and, therefore, do not exist naturally in the wild. Recent studies applying molecular markers, in addition to studying the Skull and skeletal morphology of current and mummified animals, revealed that the ancestor is most likely Cavia tschudii. [Wikipedia] | | | Hamster | Hamsters are rodents belonging to the subfamily Cricetinae. The subfamily contains about 25 species, classified in six or seven genera. They have become established as popular small house pets, and, partly because they are easy to breed in captivity, hamsters are often used as laboratory animals.
