Until you find a vet
1. Soak the snake daily in a tub with some betadine added (tea colored), for 30 minutes pat dry.
2. Apply a thin layer of neosporin (without pain killer additive)
3. Use paper towel substrate.
4. Make sure it has water, but NOT a large dish for him to soak in.
5. Monitor wounds for increased redness, swelling, and or drainage.
I hope this helps, and please keep me informed of it's progress.
