Grumpy Cat gets her own Lifetime movie

No one can bring on the bah humbug better than Internet's famed feline, Grumpy Cat. Her first movie, "Worst Christmas Ever," debuts November 29 on Lifetime.

The Grinch who stole Christmas is actually a grump -- or more specially, Grumpy Cat.

In the upcoming Lifetime movie "Grumpy Cat's Worst Christmas Ever," a 12-year-old girl wishes for a friend and finds Grumpy Cat (voiced by "Parks and Recreation" grumpy human Aubrey Plaza) in a pet store. She soon discovers they can communicate with each other for better or worse. Fortunately, even with Grumpy's bad cat-titude, the finicky feline may still manage to tap the holiday spirit.

This isn't the first time Grumpy Cat frowned around the Christmas tree. Last year, Grumpy Cat joined other cat celebrities like Colonel Meow, Oskar the Blind Cat, Nala Cat, and Hamilton the Hipster Cat to make a cool Christmas music video.

But this is Grumpy's first full-length movie with dialogue, action and even a Michael Bay-inspired explosion. The movie promises to be sappy -- hello, Lifetime -- and full of heart. Hopefully, devoid of furballs.

"Grumpy Cat's Worst Christmas Ever" will debut on Lifetime at 8 p.m. ET on November 29 in the US and on December 4 in the UK. The DVD and the music soundtrack are already available for pre-order through Amazon.
