In case anyone is interested, one of my ferrets, Baby, had a splenectomy a while back when she went in to have a mast cell tumor removed from her hind leg. Well, the mast cell tumor turned out to be a sebaceuos adenoma instead. The biopsy on her spleen came back as "extramedullary hematopoetin of an unknown origin" the usual result. She's doing great, starting to blimp out again so she's back on a diet. The Totally Ferret is great food but except with the breeders it puts too much weight on them. I'll be glad when the maintenance formula comes out. Cindy [Posted in FML issue 1132]
