Chinchillas are small, furry rodents native to South America. They have a unique digestive system, similar to other rodents, that involves a process known as coprophagy, which means eating their own feces.Contrary to what it may seem, chinchillas don't consume all their droppings, just a special type known as cecotropes. Cecotropes are soft, green fecal pellets that are produced in the cecum, a pouch located near the start of the large intestine.
