BTW, ringworm is a fungus rather than a worm and ferrets do get it. You can find info on that also in the FHL archives and i think also in the FML archives. Here are two past veterinary pathologist posts on GI tract worms in ferrets: http://fhl.sonic-weasel.org/browse.php?msg=YG3737 and http://fhl.sonic-weasel.org/browse.php?msg=YG3071 [Posted in FML issue 4702]
