One day you're a grumpy little cat, then internet sensation and finally a movie star. Grumpy Cat is a modern day Garfield and her fame isn't going away anytime soon.

Grumpy Cat is actually named "Tartar Sauce" and pretty happy with her life. Her uniquely miserable look is because she has "Feline Dwarfism" and an under bite. News has recently hit the web that Grumpy Cat will get her own movie and it will be like the "Garfield" movie so expect a mix of live action and computer generated imagery. Tartar Sauce has already made her TV debut.
