Ok here is what I know == My freind here at work used to have some & he said at the pet store you buy these mesh bags of rocks for the sugar gliders to rub their scent gland on & that is what keeps them from stinking.. You change out the bag every 3 months & they are $$.. He said you dont bath them & they clean themselves.. He also stated they are $$ to keep.. Hope this helps & Good Luck..
