Did this study look into rates of adrenal disease occurrence in ferrets of different ages of sterilization or simply the date of onset of the disease? I seem to remember this particular study looking at age of onset in ferrets who actually had the disease and not dealing with ferrets who did not have adrenal issues. Unless it looked at rates of occurrence, it doesn't seem entirely relevant to the discussion that has been going on. Can you provide the reference for us so that we can read about this study? Thanks!
