Greetings fellow ferret-parents! I am frustrated. My 3 year old male sable ferret "Fizz-Gig" still has small bare patches on his shoulders. They're about the size of a quarter and a dime. It started about 5 weeks ago at the peak of a flea infestation. He had fleas in his beds, and on his body. They seemed to all hatch at once.. I have old shag carpet, and I think that's what protected them from my vaccuuming. I gave him his first dose of Advantage two weeks ago, washed his beddings, and steam-cleaned the carpets, spraying "Safers" flea spray afterwards. The patches haven't grown or shrunk since the flea-blitz. How patient do I have to be? Is there anything I can give him to stimulate hair growth? What's this I've been hearing about FLAX oil? I hope it's not adrenal. : He has FULL, THICK hair on his tail, haunches, and everywhere else on his body. He's eating, drinking, and pooping. He's playing and alert. __BUT__: For nearly 2 years (as long as I've had him) he sometimes drags his "belly-button" across objects. He doesn't pee, but I think it's still marking behavoir. I think it's kind of a hormonal surge he gets once a month, like PMS. WHAT DO YOU GUYS THINK?????? Also, if he's otherwise healthy (except for the thin hair patches) can I still go ahead with his vaccinations? I need to get them done soon. He loves going for walks outside, and he's scheduled for Oct. 19th. I appreciate any advice anyone has. Thank you. Kris and Fizzy. [Posted in FML issue 3201]
