Greetings, I take melatonin as a sleep aid and I have been giving it to my 6 1/2 year old ferret for adrenal disease until her implant comes. She is definitely lower energy recently. Then I had a DUH moment - she is probably 'sleepy' due to the melatonin. Does it have this effect on ferrets? She gets 1ml in the morning. Please straighten me out, Shirley [Posted in FML 7519]
