For information regarding AD: AFA Medical Report--Volume 9, Number 6, 1998 Written by Leo V. Gates, III, DVM. http://www1.btwebworld.com/beechhouse/ferrets.htm An informative site and basically the only one I found. James G. Foxs' book-Biology and Diseases of the Ferret--page 360--is also a good reference. I know how devastating it can be to be diagnosed with AD. It seems that your lifes work is stripped from you. That is not the case. You can go on. It is a lot of work, but it can be done. I truly believe that AD is more widespread than the average person knows. A year and a half ago I heard relatively nothing about this insidious disease. Then it hit. Since then I have read about more and more people encountering this. Let me say one thing--your regular vet can not diagnose AD. The blood must be sent to United or MIT for the CEP test. Yes, I understand that the lesions in the spine, enlarged spleen etc. may be AD, but other illnesses should be tested for and ruled out prior to testing for AD. Hind leg weakness is a "catch-all" phrase and a lot of illnesses cause this malady. I am not a vet, but, I have been trying to collect all information I can since meeting with this terrible disease.
