Triple Antibiotic. Not trip me antibiotic. Spell correct is the worst.My Russian Tort had a little bit of shell rot when I bought her from the pet store, but it looked different from what seems to be on your sulcata. I put antifungal cream on the bad areas for a couple days and then I put trip me antibiotic ointment on it for about a week until it was gone and healed. I applied everything using q tips.
