Everyone's favorite grumpy cat, Grumpy Cat, has moved her success off the internet and into the real world.

Grumpy Cat, also known as Tardar Sauce, has been hired to be the star of Friskies cat food's latest ad campaign. Apparently, Tardar Sauce has been living it up -- flying first class, drinking bottled water and staying in posh hotels. We bet she looked miserable the whole time. Brilliant.

Has Grumpy Cat sold out? Or will she still be as funny (and as grumpy) as ever on the small screen?
