Chinchillas have a notably long lifespan compared to many small pets. In the wild, chinchillas typically live about 6 to 10 years, with most sources citing an average around 8-10 years due to natural predators and harsh environmental conditions

. In captivity, however, chinchillas live significantly longer, often between 10 and 20 years, with many pet chinchillas reaching 15 years or more with proper care

. The oldest recorded chinchilla lived over 29 years, demonstrating the potential longevity of these animals under ideal conditions

. Factors contributing to the longer lifespan in captivity include protection from predators, access to veterinary care, and a controlled environment with a proper diet. In summary:

• Wild chinchilla lifespan: Approximately 6 to 10 years.
• Captive/pet chinchilla lifespan: Typically 10 to 20 years, often 15+ years.
• Oldest recorded chinchilla: Over 29 years.

Proper care, including a balanced diet, adequate exercise, and a safe environment, is essential to maximize a chinchilla's lifespan
