The chinchilla (Chinchilla lanigera) is a small rodent originating from the Andes Mountains of South America. Chinchillas have been trapped to near extinction in their native countries. In Chile in 1918, Mathias Chapman was given permission to export a few chinchillas from Chile to start a captive breeding program. He caught only 12. These chinchillas were shipped to America and serve as the breeding stock for all of the chinchillas in today's market. 2 species of chinchillas are recognized: C. brevicaudata and C. lanigera. Only the C. lanigera were caught by M. Chapman and it is unknown if any of the C. brevicaudata exist.

Their lifespan is much longer than most rodent species averaging 10 years with 18-20 years possible in some individuals. The male averages 400-500 grams in body weight and the female is slightly larger at 500-600 grams. They are clean, odorless, and inquisitive animals and can be relatively easy to care for.

Husbandry

Chinchillas are generally nocturnal and prefer a quiet environment during the day. Chinchillas are active and require a fair amount of space. They like to jump and climb and a large multilevel cage is recommended. A wire mesh cage is better than wood because they like to gnaw. The mesh must be small enough to prevent foot and limb injury and part of the floor should be solid. Bedding should consist of Aspen or pine shavings or recycled newspaper litter. A hiding/sleep box is necessary this prey species.

Chinchillas are fastidious groomers and require dust as part of their daily bathing. The dust is a fine mixture of Fuller's earth and silver sand (1:9) and is placed in a container large enough for the chinchilla to roll around in. These baths need to be kept clean and free of feces and should be removed when not in use. Overuse of the dust bath can lead to conjunctivitis due to irritations in some chinchillas.

The chinchilla's native habitat consists of low humidity with sharp variations between daytime and evening temperatures. High temperatures and high humidity must be avoided year-round. Chinchillas are comfortable at cooler temperatures (>32F) and can suffer from heat stroke if the environmental temperature climbs above 80F, especially when coupled with high humidity.

Nutrition

In the wild, chinchillas survived on a diet of grasses, cactus fruit, leaves, and the bark of small shrubs and bushes. Captive chinchillas need a diet high in fiber to prevent enteric problems. The basic chinchilla diet consists of good quality grass hay (timothy or orchard) and a small amount of chinchilla pellets. Because the diet must be high in fiber, the sole feeding of pellets must be avoided. Limit pellets to 1-2 tablespoons per day. Small amounts of greens and fruit can be offered as treats. Any change in diet should be done gradually and fecal output should be monitored.
