Caring for Chinchillas

    A chinchilla can be a delightful pet for the right owner. Chinchillas have delicate skeletons and love to chew on things like electrical cords, so a safe environment is essential. Keep your chinchilla’s health on the right track with a healthy diet, lots of safe exercise, and regular veterinary care.

    Biological Facts

    • Long-tailed chinchilla: Chinchilla lanigera
    • Native to the Andes mountain ranges of northern Chile; live in rock crevices and holes on relatively barren slopes
    • Life span: 10 to 15 years
    • Adult weight: 14 to 28 oz (400 to 800 g); females are larger than males
    • Very delicate bone structure; not an ideal pet for small children
    • Sexual maturity: 7 to 10 months
    • Gestation: 105 to 115 days   


    • Primarily active at night, dawn, and early evening
    • Fast, agile, active; good at climbing and jumping
    • Females are dominant and more aggressive than males
    • Difficult to litter train
    • Very clean; virtually odorless
    • Highly social; should be housed in pairs or small groups when possible
    • Rarely bite; enjoy being petted, but may resist cuddling
    • They chew everything; the chinchilla’s environment must be “chinchilla proof” to prevent injuries and escape


    • Must be high in fiber, low in carbohydrate, and low in sugar to prevent dental disease and digestive problems
    • No breads, cereals, or nuts should be fed
    • Feed free-choice quality grass hay, such as timothy, brome, and Bermuda grass
    • Feed 1 to 2 tablespoons of commercial chinchilla pellets daily
    • Feed small amounts of alfalfa or clover hay, dried fruit, and fresh vegetables as treats; feed treats sparingly to prevent obesity
    • Diet changes must be gradual to prevent stomach upset
    • Provide fresh water daily


    • Provide a large, multilevel cage with shelves for perching, plenty of room for running, and a cage floor of welded mesh wire with smooth areas for resting the feet
    • Place the cage in a quiet location
    • Maintain a humidity level of 40% or lower and a temperature of 50°F to 75°F (10°C to 24°C); temperatures higher than 80°F can be fatal
    • Provide a nest box (one for each chinchilla) for sleeping and for shelter from aggressive cage mates
    • Provide wooden cage furniture, chew sticks, and pumice stones for chewing to help keep teeth healthy
    • Provide an exercise wheel with a smooth running surface to prevent injuries to legs/feet

    Preventive Care

    • A complete physical examination is required every 6 to 12 months
    • An annual fecal examination is necessary to check for internal parasites
    • Examine males monthly for penile hair rings
    • Allow regular, supervised exercise in a chinchilla-proof enclosure to prevent obesity
    • Allow a 10- to 15-minute dust bath at least twice weekly
