Hi gpm,
The cat was finally diagnosed after about 2 years for Feline Eosinophilic Granuloma Complex or commonly named Rodent Ulcer. The lesions vary a lot with this complex. It appears to be "immune related" (what isn't!). Our cat is supposed to be on life long pred or depo to "control", however we know I'm not into that! So we have been treating homeopathically, put him on raw food, my only concern would be the regrowth of mouth lesions, but so long as they stay on the body thats OK for now. This cat always had problems with stomitus and we were going to pull his remaining teeth after the lesions formed in his mouth, which we originally thought were ulcers. They were so deep, pus-filled and nasty looking that the vet decided not to waste money pulling the teeth as she was sure he had cancer. Surprisingly the biopsy should differently. We pulled his teeth and here we are today. Check out this site for pictures of the way various lesions will look. Our guy had mostly "yellow, burnt" looking lesions on the body until after merc, then they started to look smaller along body, more like the oral lesions depicted.
