A few weeks ago I posted a mail about our oldest boy Gizmo, asking you FML readers about the symptoms he was showing and if they were related to kidney problems. Thanks to the information we got, we insisted that our vet would do a fasting blood sugar test and it came out positive. The amount of glucose in his blood after 4 hours of fasting was very low. At least now we know what we are facing. His kidney problem is better thanks to the Hills diet food. For the moment he is doing quite well. The brewers yeast (recommended in the insulinoma faq) seems to help. If anyone has suggestions or experience according this desease, please let me know. Insulinoma in ferrets is not known in Belgium. Thanks to the internet and the efforts of the American ferret lovers, we are getting a lot wiser and what's most important, we are able to help our little Gizmo, which we love very much.I will keep you informed.
