I suppose the problem, then is how I expressed this finding. I was referring to the approximately 30% of intact ferrets (out of 103 in the study group) which had adrenal disease. I don't think that I could (or would) make a blanket statement that 30% of intact ferrets have this problem - I don't think there is any way to know (how would you get a statistically sound sample?) Also regarding chromium picolinate - I have heard of its use, but I don't have any experience with it.... Bruce H.
