I don't have any pics of it but i know they can get it from laying on a heat pad that is too hot and doesn't have enough material in between the bottom where the heat pad it and where your snakes lays. Just make sure that the heat pad is not on the inside of the cage, thats why a lot of breeders don't like heat rocks. If you think your snake might have it post some pics here and I'm sure me or someone else will be able to tell you.
