Let me just add DO NOT leave your snake unattended soaking in any size container. Its too risky, it says here to let soak for 45-1 hr. I put her in a tub for 10-15 minutes and it seems to do the job. So if you cant watch the snake for 45-1 hr only soak for the amount of time you can.

ball pythons who have not shed good over their heads and sensory pits will make hissing noises caused by the loose skin. This isnt aggresion or a sign of an RI, if it only happens during a shed.
