Before I forget: staring off into space and kind of weaving can SOMETIMES be early insulinoma. There's a very recent article by Charlie Weiss that finds the best and longest control to come from early corrective surgery with the area around the insulinomae as well as those tumors themselves removed. In your situation I think I'd have a fasting blood glucose tolerance test done since it keeps happening. Your vet should know about it, and you can read about it in the medical FAQ (which you should also copy for your vets) at that WONDERFUL RESOURCE: http://www.ferretcentral.org [Posted in FML issue 2496]
