Subject: Re: Mouth Cancer?
Kym, my ferret had something like what you described on her upper lip shortly before she was put down for lymphoma. She had been on pred and as it is an immune inhibitor I guess I wasn't surprised to see it. The vets told me it was (oh shoot, what was it...) well, just dead tissue. I thought it might be gangrene, but apparently it was just a non-healing mouth ulcer. It put her off food too. It was grey-white and the outside felt tough. It was very painful for her.
be sure to get him to a vet
hope this helps,
Jen
