Treats and Helping Stabilize To help stabilize blood glucose, give frequent meals and high protein snacks. You can hand feed ferrets their regular food - it seems to taste better that way. We keep kibble in every room of the house in little dishes up on tables and hand them pieces as they go by. Make sure you're feeding them a high protein kibble, like Totally Ferret. We were told by Dr. Willard of Totally Ferret not to switch our two Insulinomic seniors to the senior food, which has lower protein.
Many people swear by adding chromium and brewers yeast to the diet.
Dr. Weiss used to recommend that, but over time has not seen any evidence that there is a difference between ferrets who were given supplements and those who were not. It can't hurt, just don't rely on them as treatments. Looking Ahead and Monitoring When a healthy ferret is two or at the latest three years old, getting a fasting blood glucose test will give you a baseline or even could uncover an unsuspected insulinoma. If blood glucose tests are not conclusive, an insulin test can be done. If it's positive, it's accurate.
