Here's a helpfull Hint from Heloweasel:
 
Purchase an inexpensive plastic or vinyl shower curtain in your favorite
color.
 
Leave it on the floor where your little fuzzies can spend some quality
time with it.
 
In a few days, you'll have a lovely shower cutrain perforated with
hundereds of tiny tooth holes, a perfect ferret theme if there ever was
one.
 
For those of you wanting an added touch, leave it in a corner.  Your
lovelies will drop a few extra, uh, markings on it...
