How Long Do Chinchillas Live?

What is a chinchilla lifespan? Chinchillas live 8-10 years on average in the wild, while some well cared for pet chinchillas live as long as 20 years. For example, the oldest living chinchilla was named Radar, and he lived to be nearly 30 years of age!

Wild chinchillas live exceedingly shorter lives in the Andes Mountains due to predation, loss of habitat, and overall climate changes.

They are athletic and slightly delicate creatures with needs beyond that of the standard rodent. They are considered a critically endangered wild animal.

However, these herbivores are delightful pets, capable of jumping up to six or seven feet in the air. Like most rodents, they need constant stimulation and the ability to wear down their teeth, as they never stop growing.

If properly taken care of, most domesticated chinchillas live to be at least ten years old. Wild chinchillas have a more difficult life. Speaking of, let’s take a look at this rodent’s life cycle now for some insight.

The Average Chinchilla Life Cycle

Chinchillas have a different life cycle than many other rodents, given their unique genetic makeup and characteristics. Let’s talk more about what life is like for a chinchilla at any age or stage of their life.

Newborn, or Kits

Chinchillas have a gestation period of just over 100 days, making this fairly long in the grand scheme of rodents giving birth. However, they are born with their fur and the ability to see right after being born, another unique chinchilla trait.

Kits will need to remain with their mothers for up to ten weeks of their life. They need her for warmth, protection, and necessary development of social skills. However, kits are active and playful from their very first day on earth, making them agile and fearless!

Young Chinchillas

By the age of eight to ten weeks, young chinchillas lifespan are weaning themselves from their mother’s milk and protection. They are equal parts playful and shy, making them ideal pets for older children or even adults.

Young chinchillas should be separated from each other during this stage of their life as well, and grouped into same sex pods. This is to prevent breeding, not because chinchillas prefer isolation. In fact, chinchillas thrive in large groups- wild chinchillas are often found in groups of 100 or more!

Clean, relatively odor-free, hyperactive and lovers of attention, chinchillas can make excellent pets for apartment dwellers in the right climate.



After a year has passed, most chinchillas are considered adults at this time of a chinchilla lifespan. They may still grow a bit, especially if they are active and hungry chins. They are likely to build muscle during this time, though you can’t tell underneath all of that fur!

Adult chins are ideal companions for their playful natures and unique personalities. They are shy often, but this means they are less likely to bite. Plus, they are nocturnal and love dust baths, a process that involves them rolling around in a bunch of specially formulated dust.

There’s a lot more to learn about adult chinchillas, especially how you can extend their lifespan for years to come. Let’s learn about that briefly now.

If you are hoping to adopt a chinchilla or have recently brought one home, here are some tips to help extend the life of your new family member:

  • Feed them a high fiber diet. Chinchillas are similar to rabbits in that they require a large amount of fiber in their diet in order to live happy lives. Diet is key to taking care of just about any pet, chinchillas included. So take the time to research what foods are ideal for your new chin, and how you can best keep them healthy and happy.
  • Always give them something to chew. Whether it be a block of wood or a bundle of hay, chinchillas need the option to always be chewing. Their teeth grow nonstop, like many other pet rodents, so it is imperative to keep their teeth at a decent length.
  • Get to know your chinchilla’s personality. As with any animal, chins are known for hiding their pain or discomfort. That’s why it is key to get to know your chinchilla and how it operates normally. This will make any abnormal behavior even more obvious so that you can take them to the vet and get them the help they need.
  • Have a vet who knows chinchillas. If you are able, seek out a veterinarian who understands exotic pet care and can properly take care of your chinchilla when it is feeling unwell. While it may be a difficult search at first, finding a vet who can extend your chin’s lifespan is key!
