To Cathy Mook : I agree with Pam Greene on this one - your ferret is most likely shedding out for the spring. But , you should also keep adrenal disesae in the back of your mind - you will certainly be able to tell when the hair loss reaches a critical mass and you have to start considering adrenal disease as a legitimate possibility. If you are very very worried - you might consider pursuing the new blood test that just became available from the University of Tennessee for those difficult to diagnose cases. I think Pam has already included it in the FAQ. I don't have the phone number at my fingertips on this machine, but if you will contact me at work on Monday - I'll be happy to give you all of the info.
