Chinchillas are used in laboratory experiments for a number of reasons but a common reason is that the chinchilla has a hearing range that is closest to that of humans. Therefore many experiments researching the auditory system utilise chinchillas. Research using chinchillas has been undertaken since the 1970s. Chinchillas also make good laboratory animals as they are relatively easy to maintain, have long life spans of up to 20 years and can also be trained in basic techniques to facilitate easier laboratory techniques. Further to this viral and bacterial infections are relatively uncommon as are tumours.
