Kitty’s personality and overall character is not based on any particular cat so much as on that of every cat, every ornery and self-important cat, I have ever known. However, she is physically modeled after a cat named Zou-zou we owned when I was little. Zou-zou was a small cat, even for a cat she was small, who had the deepest black fur of any cat I had ever known all over every inch of her body except for a single, elegant tuft of white fur on her chest. When I first conceived the idea for the first Bad Kitty book and needed to decide on what she should look like, I immediately thought of Zou-zou. All I can say is thank goodness I made Kitty a black cat because I had no idea back then that just a few years later I would use her in chapter books in which all of the interior illustrations would be black and white and gray.
