None of the above! Patagonian maras are rodents native to South America. They are part of the cavy family and are related to capybaras and guinea pigs. Four-month-old mara siblings, Poa (male) and Briza (female), recently moved into their new home in My Big Backyard. The friendly duo is quickly stealing hearts with their energetic leaps, adorable dirt baths and whiskered snoots. Visit Poa and Briza during your next visit to My Big Backyard!
