I've been changing the paper towels daily and whenever I find urine or poop in the tank I soak her in the Betadine solution but the condition appears to be getting worse. The redness is spreading up her belly and also up onto her back. It doesn't seem to be affecting her much she doesn't flinch or recoil when the area is touched and she's been moving around the tank normally. Could I be doing something wrong or is this going to get worse before it gets better?
