Sirius decides to infiltrate the Granger family for Christmas, posing as the newest family pet in hopes that Peter Pettigrew will be brought right to him in time to give himself the Christmas present of revenge against the wizard who actually betrayed James and Lily to Voldemort. What could go wrong? Why, the middle Granger child suspecting there is more than meets the eye, that's what.

Disclaimer - I don't own Harry Potter. This is written for ONC 2025, prompt seven. "You've always suspected that the stray cat in your area is more than it seems. Now you're determined to catch it shapeshifting and prove it's a shapeshifter. But the closer you get, the more questions arise." Except instead of a stray cat, it's a stray Sirius. :)
