When checking the ingredient lists for treats for diabetic ferrets, also be aware that STARCH in grain-based foods (like cheerios) is just two glucose molecules stuck together. It falls apart into two separate glucoses when it's chewed/digested, and can wreak havoc with the poor fuzzie's blood sugar (blood glucose) levels. I didn't know that until we covered it in Anatomy (Human) last month. Suzanne [Posted in FML issue 2548]
