My pastel female does this, occasionally. Crawls out of her hide, gives it a nudge with her head as to say: "Hey uuuuuuh... You dead, right?" Then opens wide and starts swallowing. Head first, tail first, doesn't matter. Whatever end she nudges- she eats first.
It's pretty amusing. And I will have to def try the soiled mouse bedding trick. She's picky as it is.
