I'm glad to hear I'm not the only one that has had cats with cases of "mistaken identity"! I had a long haired grey/white stray show up and was told it was not only a girl but PG too! I named her an appropriate girl name. Several weeks later while petting her I found what I thought was a lump on her leg. Called my neighbor over (that was a vet tech and who'd said it was a girl) and showed her the lump...you guess it...her name quickly was changed to MR. FISTER...
