I need to stop trying to cram a bunch of holiday themed books in at the end of the year. Mostly because, I end up being more annoyed than entertained by the time I'm on the 3rd or 4th one.
Anyway, I think a better title would have been the 9 Tropes of Christmas. Even though most of the story was told from a highly animorphized cat's point of view, it still covered a large amount of stereotypical plots.
