"I've got three ferrets who spend half the day in a cage, I clean them often, but are always looking for the cheapest and most efficient way. The paper products usually just smell like wet paper, simliar to wet dog, hate it. I really had good luck with corn cob bedding, but I wanted to try something different again... I acutally forgot to clean them one day because there was no odor. When I first used the product there was the nice aspen smell. That was Saturday, todays Tuesday and I just cleaned them, only because I realized I hadnt cleaned them. But still no smell, and I'm finding myself using less, so I dont have to have such a giant bag to last me so long."
