Megan This may be a beginning sign of insulinoma. By 6 year old insulinomic girl Belle does this. I think it is because of excessive salivation. Take her to the vet to have a fasting blood sugar done. Fast her for about 4 hours. Different vets have different thoughts on what constitutes a low level. Mike Janke has a wonderful new web page on ferret health care with links to lots of info on insulinoma (and adrenal).
