We don't really know why it happens. There are several types of diabetes, and prednisone may result in islet exhaustion (with the pancreas striving against the hyperglycemic effects of prednisone). Certainly there are a number of cases in which animals that have been on hyperglycemic agents such as Pred or Proglycem have eventually developed diabetes. This is one of the reasons that I generally counsel surgical intervention for insulinoma rather than rely on long-term medical treatment. However the vast majority of animal on long-term pred simply stop responding to its hyperglycemic effects.

A sudden fever in a sick animal is often a sign of a developing gastric ulcer - substances from the GI tract which are banne from the bloodstream now have easy access to it. Diabetes is generally not associated with fever.

Actually, I am working with Mike Garner on the pathology of diabetes in ferrets, so the info is certainly timely and we hope that it will be useful.

We'll look at all of it, but in a general workup for diabetes, the pancreas is always the most important organ.
