Burmese ate rat backwards

[Goochie]

Hi i rescued a Burmese off someone who wasn't treating it right or feeding it enough and i've just got her eating rats the thing is she ate it backwards tonight and im scared it's going to do her harm as i've not had any of my snakes eat their food backwards before better to ask and be safe than sorry.. Next time i'm going to try putting the rats nose in warm water to see if she takes it head first every time.
