​"Yes, chinchillas need bedding," Whimsy says. "Considering their cage should be tall, a thick layer of natural, kiln-dried pine bedding acts as a shock absorber in case of a fall. Plus, pine naturally absorbs urine smells and can be used as compost after cage cleaning. And, pine bedding is safe for chinchillas to chew (unlike recycled 'fluff' beddings)."
