Hi X, Mike's website is a good place for info. The April 15, 2001 issue of JAVMA has an article about Lupron on page 1272. The U of Wisconsin is a good place to call for more info on melatonin use and benefits. If surgery is not an option then medical management with Lupron or Melatonin is the way to go. Hope that helps, Jerry Murray, DVM [Sukie note: The health part of Mike's website is http://www.miamiferret.org/fhc . ] [Posted in FML issue 3470]
