Wow, 62g is really skinny. Thank you for rescuing her. How often was she fed has she even had a meal? I would try to feed her either f/t or live (which ever she was on before) for a couple days then you can try to assist feed her. Don't force feed her just try to get the mouses head in her mouth and see if she eats it. If you arent already I would also lightly spray down her cage to maybe help her shed. Hope this helped.
