I don't have a dirt box for my fuzzies to play in. But, when I had only one ferret I used to bring her to my parents house and take her outside on a harness so she could nose around the yard. She loved to roll, dig, and run around in the dirt and moist soil near a pond. I would watch my little girl get in all the good dirty stuff, but somehow when she came out her fur was always smooth, soft, and clean! I never checked her scent, but it always amazed me that she could come out so neatly out of such a dirty area! Risa [Posted in FML issue 3796]
