Angelique-- Two of our four ferrets love playing in aquarium gravel too! One of them has always been fascinated with the smell of anything having to do with a fish tank, and has even "snorkeled" (sticks full head under water with eyes open and looks around briefly) if we will let her! Both she and her sister loved it when we drained one of our ten gallon tanks and left it sitting open with the gravel in it-- the 10 gallon tanks are the only ones (out of 7) that the ferrets can get at, and both girls would climb in and dig for hours! Laska makes a cup of her front paws and backs around and around the tank, as if she is trying to scoop up a giant pile of gravel. They are terribly funny to watch doing this! Debra in Ft.Worth Tagline space to let. Inquire within. [Posted in FML issue 0848]
