Laryssa, more and more reports of adrenal disease and insulinoma are coming from Europe and there have always been cases that fit but the treating vets thought the problems did not exist there, same as has happened in some areas with ADV on more than one continent. These short posts and one 1999 link will interest you and are best read in order from the original posts and through these replies: http://pets.groups.yahoo.com/group/ferrethealth/message/5368 http://pets.groups.yahoo.com/group/ferrethealth/message/5370 http://pets.groups.yahoo.com/group/ferrethealth/message/5382 http://pets.groups.yahoo.com/group/ferrethealth/message/5393 Important reminder for all: when researchers study possible considerations it means that they are learning IF those exist and if so then to what levels. All too often in such discussions a few people will think that is something is being studied then it somehow must be known, but actually the opposite is reality: studies are done to see if what might be possible actually does exist. Recently, I have gotten a few letters from two people saying that if something is studied then there must already be hard data which should be shared, but really things are studied to get hard data and answer questions. The data does not exist until after the work has been done.
