Chris, I have a friend who used to be on the ferret list but who changed jobs to one where he has no net access. One of his ferrets (Slinky, a nuetered jill about 4 years old) recently dropped a lot of weight quickly and started loosing hair on her back. She still has a good appetite and is active. I think that he feeds her Science Diet with linotone as a daily treat. Since we live in a state where ferrets are illegal, getting medical care is difficult. I was wondering if you could throw the powers of the net on his problem and see if anybody has theories as to what might be wrong. As usual, I would appreciate it if you maintained my anonymity. [Drastic weight and fur changes is sometimes perfectly normal... Our vet has learned not to take a weight variations (within reason) as primary indication of a problem, he looks for other signs. You might want to ensure that she's not getting more than a drop or two of linotone a day, more than that you run the risk of vitamin A overdose and probably liver and/or kidney problems. Is she passing normally? Black tarry or loose stools are indicative of problems. Though loose stools are frequently a sign of a ferret eating dairy products. Her intake and outtake should be monitored.] On an unrelated note, I just received issue 105 and the previous issue I received was 097. Could you mail me the issues I missed? [Done] [Posted in FML 0106]
