"Because she never gets chosen by customers, she develops a sour outlook on life, until one day during the holidays, a very special 12 year-­old girl named Chyrstal enters the pet store and falls in love with her after realizing she is the only person who can hear this unique cat talk," the statement continued. "As the two develop a close friendship during the holiday rush, Grumpy reluctantly thwarts the kidnapping of an exotic dog she dislikes and, on Christmas Eve, rescues Chyrstal after the mall closes. Through her adventures, will Grumpy learn the true meaning of Christmas? Or will it be, in her words, the 'Worst. Christmas. Ever?'"

'Grumpy Cat's Worst Christmas Ever' airs on Lifetime on Saturday, Nov. 29 at 8 p.m.
