There was this manga I read a long time ago, about a little girl who was looking for someone (it turned out to be her cat). It took place in France, I think?? Well, she gets into a lot of trouble looking for the cat. It was a oneshot, if memory serves. I don't remember a whole lot about it. The little girl had really curly hair, I think. I wish I could be more specific, but I don't remember that much about it.
