Harry Potter and the Hat wearing Cat
Harry Potter was walking back up to Gryffindor tower one night lost in thought. He was thinking about his childhood. One of the few good points in it in fact. He was recalling when he had managed to knick a book Dudley had thrown in the rubbish bin and red it in his cupboard under the stairs. The book? Why, The Cat in the Hat of course!
Now as Harry was rounding the corner in the corridor, who should he see, but Mrs. Norris, Filch's cat?
Now Harry, while not the prankster his father was, or the Weasley twins were, still had a sense of humor. So, when thinking of a cat in a hat, and presented with a hatless cat, what would one presume one would do?
If you assumed to show restraint and just ignore the hatless cat, well... YOU ARE WRONG!
Harry thus decided to do something better than kick Mrs. Norris. Pulling out a scrap of parchment, he quietly transigured it into a rather familiar looking top hat with red and white stripes, and with a few well placed sticking and levitation charms, managed to set it on Mrs. Norris's head before making a mad dash to the common room.
The next morning, Harry couldn't help but smile into his pumpkin juice as Filch came in clutching Mrs. Norris, howling at Professor Dumbledore that someone should be expelled or tortured, and wouldn't he look at his poor cat? This furious monologue was a met with a twinkly eyed professor stating it would eventually wear off and not to fret, and much laughter. Even the teachers were smiling a little bit.
