My children's seems to have some sort of wrinkles or lumps in the side of his neck, I've had him a couple of years and this is the first time I've seen this. He hasn't eaten in 3 or 4 months but I know this is normal, my other Ants haven't eaten either, I have a 5YO Pygmy Banded Python and a 3YO Spotted.Don't worry about the shed,he hasn't finished yet.
