Unipac Chinchilla Dust is a soft substrate, specifically created for pet chinchillas who love to take dust baths. The dust has the ideal grain size and density and is free from bacteria. Chinchillas and degus keep themselves clean with sand rather than with water. Therefore, it is essential that they are provided with a regular dust bath. However, these pets should only be provided with specifically made bathing sand and dust, as these have been made perfectly safe for them.
