Is Stuart Little a girl?

I'm curious to know, could you please clarify for me if Stuart Little, the beloved character from the children's books and films, is indeed a girl? I've heard some conflicting information and I'm eager to settle the matter once and for all. As a matter of fact, I'm quite intrigued by the idea of a tiny, adventurous mouse who just might be a female protagonist. So, is Stuart Little indeed a girl, or is this a misconception that needs to be cleared up?
