💚 How to Help Your Chinchilla Live Longer

Cool Environment

Chinchillas overheat above 75°F. Heat stroke is a leading cause of death. Keep rooms cool.

Unlimited Timothy Hay

Hay keeps ever-growing teeth worn and digestive system healthy.

Dust Baths

Regular dust baths (not water) keep their dense fur healthy and prevent fungal infections.

Low Sugar Diet

Avoid fruits and sugary treats. Chinchillas are prone to dental disease and GI upset.

Minimal Stress

Quiet environment, gentle handling, and consistent routines reduce stress.
