Hey okay so I have the same question
my snake was dull in colour and her eyes were cloudy and blue and I know these are all signs of a shed. And I woke up this morning and her colour was shiny and bright and Her eyes were normal. Yet I checked her entire cage and no skin. I know for a fake her eyes were blue and cloudy cause I took a picture and nobody removed the skin. The only conclusion I can think of is she ate it. But that's so weird. I don't understand
