Please disregard everything this person said. Cleaning with a bleach mix, betadine water soaks and neosporin?? really....:colbert:. My guess is its poop or sometimes the Urate can be a bit big and can be hard to pass, but it will pass. You can gently massage your snake while holding his lower half in some luke warm water and you will be able to feel the hard urate ball in there. Plus the massage will help him pass the stool.
