Animal fun fact: Chinchillas can’t get wet. Their fur retains too much water and will start to grow mold. So they bathe by rolling around in dust.
Chinchilla fun fact: Chinchillas have around 20 hairs per follicle; unlike humans who have 2-3 hairs per follicle. Because their fur is so dense, they cannot get fleas or other parasites. The bugs will suffocate in their fur.
