I have a 5 year old female ferret that is experiencing an unusual degree of hair loss. Blood work performed by our vet indicated that all parameters tested (including cortisol) were normal except for the blood glucose which was found to be 30 mg/dL. Our vet believes that this low glucose value indicates the presence of a pancreatic tumor and has suggested that an ultrasound be performed to allow for an estimation of tumor size. I would like to know if a blood glucose this low would be evident in the ferrets behavior (lethargy, increased appetite etc). My ferret appears perfectly normal. She is very active and playful and has a normal appetite. Does anyone know if there should be symptoms associated with low blood glucose? I think that the blood glucose should be repeated to determine if the first test was accurate. Does anyone have any suggestions or experience with this problem. Thanks, Tony [Posted in FML issue 1119]
