"A Very CatDog Christmas" (incorrectly titled "A Very Merry CatDog Christmas" on iTunes) is a special half-hour Christmas episode of the Nickelodeon animated series CatDog, produced in the show's second season.
Cat does the unthinkable in attempts to have access to more stuff on Christmas: selling Dog and himself to Rancid for his niece Rancine who has everything BUT a CatDog. Santa Claus is very angry by this and cancels Christmas entirely. Nearburg is outraged when they find out it's Cat and Dog's fault and picket through the town searching for them.
Cat and Dog, stuffed in a box, waits to be opened by Rancine. They are her only Christmas gift this year. When they pretty much become Rancine's prisoner, Cat realizes he was wrong, and they attempt to escape. However, going home isn't the best idea because Winslow, Eddie and the Greasers are waiting for them to arrive to confront them about canceling Christmas. CatDog is totally oblivious to the fact that Christmas was canceled...
The episode made its home video debut on the CatDog: Season 2, Volume 2 manufacture-on-demand DVD set, sold exclusively on Amazon.com in late 2010. It was later included on the retail release, CatDog: Season 2, Part 2, distributed by Shout! Factory on September 25, 2012.
