The Counterintuitive Reason Chinchillas Bathe in Dust, Not Water

Quick Take

• Not all dust is safe for chinchillas. Using the wrong kind can trigger respiratory damage and fur destruction, even if it looks identical to the right kind. Find the right dust type →

Dust baths are typically an activity that bird species participate in. However, several mammals enjoy dust baths for a variety of reasons, including parasite control, hygiene, and even maintaining healthy skin. One such animal is the chinchilla. These fluffy rodents roll in dust rather than bathe in water, for all the above reasons. But the biggest reason of all is that a water bath can be detrimental to their health.

Chinchillas Cannot Take Water Baths

To maintain their soft fur, chinchillas take multiple baths per week. These are not water baths, however. Instead, chinchillas take dust baths.

Chinchillas have thicker fur than any other land mammal, containing 60 to 80 hairs per follicle. To put this in perspective, humans have just one to three hairs in each follicle. Because of this density, water baths are not an option.

Were chinchillas to take a water bath, their two layers of fur would take an extremely long time to dry naturally. As the fur and skin remained wet, they would begin to harbor bacteria and fungi, causing both fur rot and skin infections.

Additionally, chinchillas lack the ability to pant or sweat. Therefore, if they become immersed in water, they risk hypothermia or even heat stroke.

Because of these adverse side effects, chinchillas take dust baths instead. The dust keeps the fur and skin clean by removing oils and dirt. There is no risk of their insulation becoming compromised, and the fur remains silky and smooth when regular dust baths are taken.

What Type of Dust is Best for Chinchillas

When it comes to chinchilla baths, not just any dust will do. Owners must purchase specific dust that to keep their chinchillas in tip top shape.

Chinchillas need dust that is made of fine particles that can absorb oils from the fur and skin. Typically, this is dust from volcanic ash, aluminum, or pumice stone. Regardless of which option is chosen, it needs to be fragrance-free.

The reason sand and larger particle dust cannot be used is that it will cause skin irritation and/or damage the fur. In some instances, chinchillas have even experienced respiratory issues as a result of the wrong dust being provided to them.

Once the correct dust is chosen, it should be poured into a receptacle at a depth of two inches. The container should be large enough for the chinchilla to roll around with ease, with a recommended diameter of 10 to 12 inches. This dust can be used up to three times before being discarded. However, if clumping occurs, the dust should be thrown out before this time.

Why Can’t Dust Baths Be Left in Chinchilla Enclosures?

Despite dust baths being the best way for chinchillas to clean themselves, keeping a dust bath in an enclosure around the clock can be too much of a good thing. There are limits to how often chinchillas should clean themselves in dust baths to remain in optimal health.

If a dust bath is left in an enclosure around the clock, the chinchilla may roll around in the dust too frequently. Should a dust bath occur too often, the consequences can include:

• Dried out skin
• Irritated eyes
• Dirty dust breeding bacteria
• Matted fur

Chinchillas should be offered a bath two to four times per week, depending on their activity level. The dust baths should be kept in the enclosure for no more than 30 minutes. This is ample time for chinchillas to bathe if they choose to.

Quality care and appropriate access to dust baths result in an enviable coat and a healthy chinchilla.
