That's how I got bit the other day...my Kenyan was still hungry (I gave her a smaller pinkie than normal b/c the rat pups looked a little large for her) after she ate the pinkie I gave her a few minutes then went to get her out of her feed tub. She struck me as soon as my hand was in there. I gave her one of the larger pups, she ate, and was fat and happy. No striking.
