Chinchillas are crepuscular (most active around dawn and dusk) rodents, slightly larger and more robust than ground squirrels. They are native to the Andes mountains in South America and live in colonies called  herds  at high elevations up to 4,270 m (14,000 ft).
Many chinchilla owners decide to get another chinchilla at some point. Even if you don't plan on putting the chinchillas in the same cage there are a few things you should do once you have your new chin. Do a quarantine! A quarantine is when you keep your new chinchilla away from your current chinchilla.This is done in a different room and have no contact between the new chin and exsisting chin(s). You should ALWAYS wash your hands between dealing with either the new chin or current chin(s).ealth is just one reason to do a quaratine. This ensures if your new chinchilla has an illness it will not be passed onto your current chin(s). Some illnesses take time to show up and doing a 30 day quarantine will give you time to see if your chinchilla has any issues.
