The best bathing sand for hamsters, as rated by Hamster Society Singapore's Ultimate Starter Kit.

Witte Molen Top Fresh Chinchilla Bathing Sand is a 100% natural, dust-free, germ-free product. This very soft sand penetrates the fur to absorb excess surface oils. Daily bathing in Top Fresh sand keeps their coats clean and healthy. Suitable for hamsters, degus, and gerbils. 

Please note that this product is not suitable for chinchillas. Chinchillas require dust baths as sand grains do not penetrate their thick coats effectively and may cause skin irritation and/or infections due to the larger particle size.
