Plaza will be bringing the grumpiest kitty's thoughts to life when the film titled 'Grumpy Cat's Worst Christmas Ever' airs on Lifetime this winter, according to Hollywood Reporter.
The original actress cast to provide the voice of Tardar Sauce was Jane Lynch of 'Glee' fame, but she dropped out last month, leaving Plaza to fill her shoes.
Plaza is best known as the moody intern April Ludgate on NBC sitcom 'Parks and Recreation', but has recently starred in films such as 'The To-Do List' and 'Life After Beth'.
The film's plot centers on a cat at a pet store who is always passed over, and the twelve-year-old girl who can communicate with her.
It looks like Tardar Sauce could give Garfield a run for his money, and Plaza is following in the footsteps of acting legend Bill Murray, who leant his voice to the famous feline for not one but two movies; 'Garfield' in 2004 and the sequel 'Garfield: A Tail of Two Kitties' in 2006.
