Guides and gear for exotic and small pets
Pet chinchillas usually live 12 to 15 years, and well-kept chinchillas can reach 20 (Iowa State University, MSD Veterinary Manual). That makes them one of the longest-lived small pets, so plan for a commitment closer to a dog’s than a hamster’s.
How old is your chinchilla in its life? Enter its age in our pet lifespan calculator to see its life stage and roughly how much time it has left.
Most early deaths come from three problems you can largely prevent: overheating, dental disease and a poor diet.

Chinchilla lifespan at a glance
| Situation | Lifespan |
|---|---|
| Pet chinchilla, average | 12 to 15 years |
| Pet chinchilla, upper range | Up to 20 years |
| Wild chinchillas | Shorter and poorly documented; both wild species are endangered |
What affects how long a chinchilla lives
1. Heat
Chinchillas come from the cold, dry Andes and cannot sweat. The MSD Veterinary Manual puts their comfort range at 65 to 80°F (18 to 27°C), and heatstroke becomes a risk above that, especially in humid rooms. A simple rule from the same source: if the temperature in °F plus the humidity percentage tops 150, the room is dangerous. Keep the enclosure away from windows, radiators and direct sun.
2. Diet and teeth
Chinchilla teeth grow all their lives, and dental disease is one of the most common health problems vets see in them. Unlimited grass hay, such as timothy, wears the teeth down and keeps the gut moving. Add 1 to 2 tablespoons of chinchilla pellets a day and keep treats to no more than 1 teaspoon a day (Iowa State University). Sudden diet changes can cause bloat, so switch foods gradually.
3. Enclosure
Chinchillas jump and climb, so height matters as much as floor space. Choose a tall, multi-level cage with solid shelves and narrow wire spacing (about 15 mm) to prevent leg injuries, plus a hide box and safe wooden chews.
4. Dust baths
Chinchillas clean their dense fur by rolling in dust, never water. Offer about an inch of chinchilla bathing dust 2 to 3 times a week for up to 15 minutes, then remove it. Bathing too often can irritate the eyes.
5. Exercise and handling
Give daily time out of the cage in a chinchilla-proofed room, or a large solid-surface wheel sized for chinchillas. Handle them gently and support their body; they can shed patches of fur (fur slip) when grabbed.
6. Vet care
Find an exotics vet before you need one. Signs to act on fast: drooling or a wet chin (often dental), not eating, small or no droppings, and lethargy on a warm day.
Long-tailed vs short-tailed chinchillas
There are two wild species. Pet chinchillas descend from the long-tailed chinchilla (Chinchilla lanigera). The short-tailed chinchilla (Chinchilla chinchilla) is rarely kept. Both have declined in the wild after decades of hunting for their fur, which is why wild lifespans are hard to pin down.
Chinchilla lifespan vs other small pets
| Pet | Typical lifespan |
|---|---|
| Chinchilla | 12 to 15 years, up to 20 |
| Guinea pig | 5 to 7 years |
| Hamster | 2 to 3 years |
Chinchilla lifespan FAQs
How long do chinchillas live as pets?
12 to 15 years on average, and up to 20 with good care.
How long do chinchillas live in the wild?
Wild lifespans are not well documented. Predators, hunting and habitat loss mean wild chinchillas rarely live as long as pets.
What do chinchillas usually die from?
Heatstroke, dental disease and digestive problems such as bloat and constipation are among the most common causes of illness and early death in pet chinchillas.
