This is my first time posting and am so glad to have found this board. I have a 2 1/2 year old Himalyan, Frankie, who has a VERY bad case of feline acne/dirty face/facial dermatitis. His condition started out with a few black crustings under his chin last year but quickly moved to his entire face, ears and eyes. His eyes are so bad that they are crusted shut. I have to clean his face and ears at least twice a day, but it continues to come back and his face becomes raw and bleeds. We've changed his food, bowls, litter, etc. We've tried 5 different antibiotics which work for awhile and then the crustings come back. He's received steroid shots and ivomac shots which seem to help the inflamation, but then the crustings come back. He's been tested for mites, mange, ringworm with negative results. Ive had him checked by a feline dermatologist who just prescribed another antibiotic which didnt help. My vet finally performed a very expensive biopsy on his face and the results indicated that he had 2 severe bacterial infections with unknown causes and resistent to most antibiotics except cipro which I just started giving him along with another steroid shot given by his vet. So now I wait and see what happens. The frustrating part is that throughout the year, he's had weeks when it's cleared up completely, but then it comes back with a vengence. Good luck to all of you and your cats and I definately will keep you posted on Frankie's progress.
