I would have thought that anyone who has studied ferrets would know more about the workings of the luteinizing hormone which is a gonadotropic hormone that is secreted by the anterior pituitary; stimulates ovulation in female mammals and stimulates androgen release in male mammals. In my opinion ferrets that do not get a regular amount of complete darkness and ferrets that are altered do get adrenal disease which I have not seen in intact ferrets and where ferrets are kept in naturale light, I have put this theory forward on several occasions and have just been laughed down by so called experts -- Please contact me I can be of any help, I am not a vet and in the past 30+ years none of my animals have visited my vet for anything other than routine check up. http://groups.yahoo.com/group/intact-ferrets/ Come see my ferrets http://www.geocities.com/houseferrets13uk/Tonys_Pets.html Some of our fund-raising events http://www.geocities.com/houseferrets13uk/Show.html http://www.webspawner.com/users/ferretwelfair/index.html http://www.headway.org.uk/ The brain Injury association The First Successful Libel Case http://technology.guardian.co.uk/news/stor...1737001,00.html [Posted in FML issue 5214]
