Thanks to everyone who responded to my post on the infection(?) in my Claudia's throat. Is there any vets who can explain in depth what a "keratinizing epithezial cyst" is? Also, to Barbara Carlson and James Hensley: How old were your ferrets at the time that you recognized the spot and how old were they when the problem was remedied? Did the spot ever change colors? Thanks again for all the help Bido [Posted in FML issue 1650]
