Prone to excited sounds, chinchillas will also emit chirps and calls according to their mood. Over time an owner will hear a multitude of these orations--all indicating the animal's personal state. A soft cooing might indicate playfulness and comfort. A very quiet chirping can be heard while the chinchilla is exploring a new place. Some sounds will originate from the grinding of teeth, which they will sometimes do after eating. They do sneeze audibly, sometimes from the fine dust in their bath. If a chinchilla feels threatened, a high and loud bark will be heard, much like a squirrel can bark. A last resort will involve the chinchilla standing on hind legs and emitting both a bark and a stream of urine.
