Most chinchillas will sleep soundly through the night or through the day depending on the specific chinchilla. However, don’t be surprised if you hear them making a small, faint growling noise. This is most likely a snore. Like people, animals including chinchillas can snore. In most cases the snoring is caused by a minor obstruction in the nasal passageway. The air in the passage way must squeeze through and sends along a vibration which comes out as a snoring sound. This may stop if the chinchilla repositions himself while sleeping. If the snoring is excessive and happens all of the time then you should contact your vet and schedule a checkup. Your can check to see if the chinchilla has any other health conditions and determine if the snoring is common or if it needs medical attention.
