By the time I got to the top of the hill I was really shivering, my now black hair had caught snow flurries, and would occasionally fly off with the gust. I walked into the mouth of the cave, and the shaggy black dog was nestled up near a small handmade campfire.

"Dad?"

I whispered, crouching next to him. The dog groggily looked up, and saw me, turning into Sirius.

"Sidney, what are you doing here, it's bloody cold, and I don't want you getting sick."

"I came to bring you back to Hogwarts with me." I said. "All I need to do is transfigure you." I pulled out my wand.

"Are you sure you know what you're doing?" He asked skeptically.

"I swear, I'm McGonagall's top student next to Hermione."

"Okay."

I flicked my wand, and in a swirl of bluish green light, there was a fluffy black cat lying on the ice-cold floor looking up at me.

"Okay, get in the bag, I'll leave the flap open so you can breathe." He got in, and contently meowed.

I trudged down the hill, and turned us invisible, walking back though the oak doors, and into the common room.

"I thought you were staying with him?" Said Hermione. Harry and Ron looked completely puzzled.

"Here he is, he's staying with us instead."

I opened the bag, and let Sirius out into the table, a gigantic poof ball of fur. It meowed at Harry.

"Brilliant! Harry exclaimed. Now he can spend Christmas with us!"

"Let's go down to the Great Hall, and grab some food." Sirius meowed, and jumped eagerly into the bag, and meowed again.

I laughed. "All right, all right, we'll hurry." We hurried to the great hall, and Sirius kept eyeing Dumbledore.

"He knows," I whispered. "He does?" Chorused Harry, Hermione, and Ron all at the same time.

"How else could we have him here?" I asked.

The feast began, and we ate, and let Sirius go at it.

He kept gnawing at a giant piece of Turkey, trying to put it in the bag.

I looked at him. "We'll take care of it." At that he ate it, and ate the rest that he happened to manage into the bag. He meowed, and licked the plate clean.

Everyone was looking at us strangely. Dumbledore kept smiling.

Once the feast was over, we went back into the Common Room, and played Chess, and anything else really, while Sirius got a chair in front of the fire, curled up, and fell asleep.

"I can't believe my dad's a cat." I whispered looking at him.
