My daughter's Ball Python developed a line of raw skin along its back, starting about three inches behind its head and travelling for about seven inches. The wound is not bleeding but I can see raw flesh where some of the scales are missing. There are a few red patches. My intuition tells me that Uday rubbed it raw against some portion of his cage. I just hope it is not some rot or disease that is more serious. He doesn't seem to have any other symptoms or problems. He did eat three mice about five days ago and regurgitated a good portion of them today. It seemed to be mostly hair. I have applied Neosporin to the wound to promote healing and prevent infection. I have also replaced all the metal screening with softer fiberglass screening to prevent more damage. Does anyone have anything to offer in the way of diagnosis or treatment?
