To Janice concerning V'orri Janice - there is no post-surgical medication in the vast majority of cases. Because the tumors secrete estrogen rather than corticosteroids, as in cats and dogs, post-surgical steroid administration is not required. All of my ferrets that have undergone this surgery required nothing more than a few days of antibiotics to prevent infection from surgery. Bruce Williams [log in to unmask] [Posted in FML issue 0715]
