So many thanks to John and Tony for knowing what the Canadian glucose numbers worked out to and how to convert, and then being good enough to help all by sharing it. At 38 unless the test was botched up the ferret is well into insulinoma. Even fasted it should not be below 65. The ferret probably adjusted to it, and the meat diet could have hidden it by helping the ferret with more gradual providing of glucose. Your posts should help that Liz greatly!
