In modern times, chinchillas are commonly kept as pets, although they are still popular in the fur industry as well. Virtually odorless, hardy, and unafflicted by fleas or other pests, these large-eared rodents may live for more than 20 years when properly cared for. They require little living space and may be safely kept in a small, clean cage, subsisting on food pellets, timothy hay, alfalfa, and water, though they also appreciate treats, such as dry oatmeal, apple slices, and sunflower seeds. Chinchillas do need regular exercise, however, to maintain good health and often enjoy cage wheels or running balls. Today, a variety of chinchillas are available in pet stores since both short- and long-tailed species exist and through selective breeding a variety of coat colorations have been developed.
