It didn't affect her in anyway, in fact most morning when I went out to let her out for the day the mouse would be sleeping underneath Sophie and suddenly run out when Sophie moved to see me. Unless the mice have the plague they won't hurt the rabbits, as long as its not a whole colony that could make your neighbours upset with you I would just leave them be.
