I have two ball pythons in the same cage, last night my het albino was in the shedding process so i let her be and went to bed. I went to school this morning and when i got home she was shed and the skin was no where to be found. I shifted all the coconut husk to see if it was buried under, and took all the hide spots out. My conclusion is they do eat their own skin, due to the fact my parents wont even open the cage let alone take the shed skin out. I am very surprised because they usually shed in one big piece and I searched the tank everywhere for it and it didn't turn up.
