Guinea Pig is different - pls do not misunderstand
The Guinea pig (also commonly called the cavy after its scientific name) is a species of rodent belonging to the family Caviidae and the genus Cavia. Despite their common name, these animals are not pigs, nor do they come from Guinea. They are native to the Andes, and while now extinct in the wild, they are closely related to several species that are commonly found in the grassy plains and plateaus of the region.
