Our Timmy had surgery for adrenal then had the Deslorelin implant.... 10 months later he ruptured his spleen and was at deaths door...again surgery was the only answer. he recovered well and it looking the best he ever has....i am sure that the Implant helped him survive.. The implant should stop all hormones being produced and symptoms will not be masked as they shouldn't be occuring becuase the disease is halted....when the implant wears out the symptoms may return...but this is not a definate. Personally i would implant anyway... my other ferrets have the implant even thou they have not shown any symptoms of adrenal. I have been on the recieving end of the human equivalent of the implant and i can vouch for the drug. Hope this helps [Posted in FML 6992]
