I was wondering if a Mouse page should be created? There is already a Rat page, but it displays info for rat enemies. In Order of Ecclesia, Anna sends you on a quest to fetch a mouse for her cat, Tom; so it's basically an "item" you can get in the game. In Rondo of Blood, there is one room where you can see (and even kill) a mouse, but I don't remember excatly if it is really a mouse or a rat. I can't also remember if there are other instances of mice appearing in the rest of the series.
