Our male sphynx Anubis had this brownish/blackish fungus that would grow on his nose. The vet never figured it out, and because we were slowly losing him to HCM we never focused too much on it. He had so many other health problems, and it didn't seem too important. You could scrape it off his nose, and the hair underneath would be missing, and the skin would be slightly red. We tried Lotrimin on it, and then a zinc based gel from the vet. Neither showed any sign of fixing it, so we just left it alone. He's been gone almost three months now, and all of the sudden one of my females has the same thing in spot a little smaller than a dime on her forehead above one eye. It showed up last Thursday, and it looked like a scratched red spot; we just assumed she had played a little rough with one of the other cats. It slowly darkened, and just like with Anubis, you can scratch it off and it grows right back. I have no clue what this is, and it worries us. Has anyone else had experience with something like this?
