Hi Mike. Regarding Buttercup, my little Butterscotch also had adrenal tumors removed some years ago...it was in June as well and it took several months before her hair grew back on her belly. We gave her pet-tinic, which seemed to help. The vulva thing also took some time to go down, but we were happy to report that the following Spring, it did not enlarge or have a discharge. Good luck. Cindy. [Posted in FML issue 0669]
