Perhaps this is the most unpleasant and repulsive feline person, well, among the "potteromans" for sure.. She did her best to be disliked not only by Hogwarts students, but also by many teachers.
Mrs. Norris is a spy on all fours, who reports to her master Filch absolutely all the minor pranks of children, but she especially keeps a close eye on Harry. And when Filch's cat appears on the pages of a book or in the frame of a movie, I want to say: "Oh, no, again this nasty cat, which will now bring Filch or get out of here!". In general, not a cat, but a little whiskered sneak.
But has she earned the dislike of Harry Potter fans? What do you think?
