When handling your pet snake shedding its skin, you should ensure that you provide a humid environment to help with the shedding process. You can also gently mist the enclosure with lukewarm water to increase humidity. Avoid handling the snake during this time as it may be more stressed and sensitive. Make sure there are no rough or sharp objects in the enclosure that could damage the new skin. After the shedding is complete, you can remove the old skin from the enclosure and monitor your snake for any signs of retained shed, such as pieces of skin stuck on the eyes or tail.
