That chinchillas, if they are good cared, can become up to 20 years is well known. But at Ute R. in Bochum Chinchi-Opa lives, and he is 21 years and 6 months old. Maybe because the three other chinchillas that live at Ute R., keep him young. The animal lover, that besides the rodents from the Andes also has a sea- and a freshwater-aquarium and a terrarium with a certain kind of frogs in the meantime also got a cat. So Chinchi-Opa will not get bored.
