She's probably not after the mold, so much as the residual soap.
 
It's common for ferrets to eat soap... don't know why... have never seen
Bob Church speculate, even, lol.  A small amount of ingested soap won't
hurt.  Smudge prefers my rose scented guest soaps, Sanka likes the
Coast... she's a little kooky, tho, she'd just as soon have the chewy
bath mat... we can't have bath mats in the tub because it's a part of
their free-roam area *sigh* (another case where ferret safety has somehow
managed to supercede human preference... have to use the stickies, that
they pull up and I have to replace frequently)
