Sounds like you are doing the best for Rocky. I have two additional suggestions: Have you tried diazoxide? I have had very good results with it - generic as well as name brand. Also, towards the end, my ferret vet suggested adding some high sugar supplementation to their duck soup/chicken gravy ... like a bit of karo syrup. She explained that it does not cause wild up and down swings in the sugar levels as it does in people. [Posted in FML 5617]
