What padding does the golden bear (hamster) use in hot and humid weather?

Cat litter, the kind without lime, recommends Jieshan brand. In fact, even in winter, I spread sawdust in half space and cat litter in half space. I have raised this for many years, and I feel very good. The rest area is covered with sawdust, and the activity area (drainage area) is covered with cat litter. After urine caking, you can shovel it off directly with a small shovel.
