2 of my ferrets have had adrenal disease. Trouble was inoperable and was medicated, he lived for another 10 months until we had to put him down because his prostate grew uncontrollably and he lost the ability to go potty. Sebastian had the surgery last November and came thru relatively well, his recovery was quite slow and he is only now getting his hair back where he was shaved. He is a happy boy though and so is his mommy.
