In the U.S., guinea pigs stand alongside hamsters, cats and dogs as beloved family pets, but that is not the case in Cusco. Rather than snuggling these furry rodents, Cusco natives see them as a tasty treat, and you will likely see Cuy, the Quechuan word for guinea pig, listed on the menus of many local restaurants. Native to Peru, these rodents reproduce and grow quickly, making them a cheap food source. Luckily, they are rather tasty as well.
