Mookie (3 1/2, neutered male) had recently developed a sort of lump on his chest. It's about 1/4" across, maybe 1/16" thick, kind of looks like a scab. It's definitely in the skin, not the muscle, and doesn't seem to cause him any pain or itching. It started off pinkish a few weeks ago and we though it might be a bug bite, but it hasn't improved, although it doesn't seem to have gotten any worse. He's otherwise in good health. We're going in to the vet next week for a regular visit, but I was wondering if anyone might have an idea. We're thinking either a mast-cell tumor, possibly melanoma, or it might be a wart, or just a slow-healing cut or something. Surgery to remove it will be about $100 (Cdn) and a histology, if necessary, another $100. With 4 ferrets getting a little older, we don't want to spend a lot of money unless absolutely necessary. I'd appreciate an opinion from one or more of our FML vets, if you have the time. Thanks in advance. Stan, Terrie & Jen, with Mookie, Psycho, Cecil & Cocoa in Toronto [Posted in FML issue 1584]
