Subject: Re: Yet Another Insulinoma Case?
             I'm one who has had a ferret that had a blood glucose in the high 
20's to low 30's who acted relatively normal with these readings.  
Beasley's wasn't always that low, but it was regularly below 60.
I think, but don't know for sure, that it might be related to how 
quickly the level drops to the current state, be that 30 or 67.  
Beasley's blood glucose was always low, and no amount of meds or high 
quality diet brought it up.  But it was probably such a gradual drop 
over the course of a year or more that perhaps his body acclimated 
itself.  Just a guess, but I can tell you that he never ever had a 
seizure that I was aware of.  Although there was never more than 4 
hours between times he was checked, fed, etc.,  they could have 
occured during that time.
On the other hand, if your ferret's was in the 90's or 100's and it 
suddenly plummited to 67, that may be why you saw the drastic 
reaction.  Also, you gave him sugar just prior to the ER visit so 
that may have helped to give an unreliably high reading.  It could 
have been much lower prior to that.
