Sand has been our only bad experience. Oh, it was fun enough for the ferrets, they LOVED throwing sand all over the room! But it was sooooo hard to clean up, and the ferret room floor, even when the sand was swept/vacumed up every day, was always sticky. Plus I would track it to other areas. At that time the ferret room was next to a carpeted floor, which has now been changed to vinyl, but I'm not sure I'd do it again. Maybe... I'm not one to deny my ferrets fun experiences, and we have ferrets now that are new since the sand days. We started with dry sand, purchased from Toys R Us, and after the first week of daily sweeping up a pint of sand from the floor, I tried wetting it. The ferrets thought it was lots of fun to dig holes and see them fill with water. Sharon has some pictures of Kouri in the sand, she may put them up on his web site. So the bottom line is - it's very messy, but lots of fun. Georgia - the left coast one... [Posted in FML issue 3409]
