About two weeks ago I cleaned out my snake's cage and put all new substrate in it and a few days later she dug it up and burrowed inside. About a week ago she finally ate after going about two weeks without eating and than burrowed under again. In the last five days my snake seems to have dissapeared somewhere in her substrate and doesn't feel like coming out. Does this happen often? Should I be worried? She is about 11 months old.
