I laugh every time I see Grumpy Cat on Facebook.  You have to laugh!  She just brightens my day, even though she'd probably hate that if she knew it.

Grumpy Cat, whose real name is Tardar Sauce, shot to fame last September after a post on Reddit revealed her permanently grumpy face to the world.

Now, cat food company Friskies has decided to make the feline the star of its latest commercial campaign.

It's hard to tell if she smiled for the cameras...take a look.

See all of her photos on the Friskies Facebook page.
