Keep your little critter clean and happy with regular dust baths. Super Pet Critter Bath Powder is made of 100% natural volcanic mountain pumice and is non-toxic and hypoallergenic for your pet's benefit. Give your chinchilla, gerbil, or dwarf hamster a dust bath twice a week, more frequent if living in a humid climate, to keep its coat soft and clean. For your critter's health, do not leave the dust in the cage indefinitely; discard approximately five minutes after use. Use fresh bath powder for each bath. 14 oz.
