Chinchillas
Felix and Oscar came to the zoo in 2010. On average they live up to 20 years and weigh up to 2lbs. In the wild they can be found in the rocky slopes of South America. Their red blood cells hold more oxygen than any other rodent because of the high altitudes they live in. Primarily herbivores and these two love to eat hay. Chinchillas have the densest fur in all land mammals but is still extremely soft to the touch.
FUN FACT
Chinchillas have open-rooted teeth, meaning they continuously grow throughout their lives. This is why they need to gnaw on wood and other safe materials to wear down their teeth and prevent overgrowth.
