Chinchillas live quite long

Indeed, chinchillas have an average lifespan of 10 to 20 years, but a handful have defied expectations by living for a whopping 30 years while being held prisoner! Chinchillas credit their ability to live a long and healthy life to their extraordinary adaptations.

Their fur, for example, is astonishingly dense and expertly insulates them against the harshest of temperatures, wrapping them in a cocoon of warmth within their native abode. South America's spectacular Andes Mountains. This adaptation protects them from the elements and serves as an effective defense mechanism against their unrelenting predators.

Chinchillas have a variety of endearing physiological characteristics that contribute to their lifespan. Consider their increased metabolic rate, which allows them to absorb food and extract essential nutrients more efficiently. Their large cecum, a specialized component of their digestive system, expertly aids in digesting a fiber-rich diet. This, combined with their natural proclivity to consume a herbivorous repertory of grasses and hay, contributes to their overall well-being.
