It won't be much of a stretch for Plaza, who is best known as playing the monotone curmudgeon April Ludgate on Parks and Recreation. Grumpy Cat could very well be April's spirit animal.
In Grumpy Cat's Worst Christmas Ever, premiering November 29 at 8/7c on Lifetime, Grumpy Cat stars as a pet store feline who's never chosen for adoption — which leads to her sour outlook on life. Along comes a 12-year-old girl, who can actually hear Grumpy Cat talk. The two eventually go on adventures together and, yes, discover the true meaning of Christmas.
Grumpy Cat — whose real name is "Tardar Sauce" (really!) — has become a superstar with 6 million Facebook friends, two books in print (including the recently released The Grumpy Guide to Life: Observations by Grumpy Cat) and merchandising deals such as one as the official "spokescat" of Friskies. Jane Lynch had previously been rumored for the part.
