Well, even though it appears that I am talking to myself, I promised an update so here it is.
Mickey's gums are swollen and it has nothing to do with baby teeth (like I hoped it was that simple). He is being re-tested for FIV as this could be the root of his problem. I won't know until later today. He will go on antibiotics and a gel that goes on the gums. Steroids will be next if the antibiotics do not work.
