Oh, Mary! Feel free to post over me if I ever say anything that gross again! I had never even really thought of Vaseline as what it is, something that forms under a salt dome, and floats on top of a lake of PETROLEUM, something I would not feed a ferret! Thank you for pointing that out. (Applause for the plant lady) Does anyone know what the active ingredient is in hairball remedy? I'm always happy to save a few bucks, but I don't really want to be feeding HYDROCARBONS, now do I? Great, flaming ferrets Batman! Alexandra in MA [Posted in FML issue 4481]
