Tame wild Wood Mouse washing herself in my hand

This is a little mouse I rescued from my cat. I looked after her for a few days until she was well enough to be released. It was very tempting to keep her, given how adorable she was and tame she became....But she wasn't injured at all, so I felt that she belonged back in the wild. I called her Peanut, because when I first rescued her I had to put her in my glove....She stayed in there for a long time before chewing her way out! And she looked like a peanut inside the finger of my glove! Plus, she loved eating the peanuts I gave her :-)
