Kaytee Aspen Small Animal Pet Bedding For Pet Guinea Pigs, Rabbits, Hamsters, Gerbils, and Chinchillas, 52.4 Liters

Has anyone used this product for outdoor cats/bedding?

My dwarf hamster seems to be chewing it and it almost looks like he's eating it, should I be worried and/or change the bedding?

Can this be used for cat litter?

Is this bedding dust free?
