PHOTOS: Grumpy Cat meme

The SXSW music, film and interactive festival has many high-profile attendees, including keynote speaker Tina Roth Eisenberg, but the biggest hit so far has been a furry friend.

Grumpy Cat is stirring things up in Austin, Texas.

The cat became an Internet sensation last fall with photos of her grouchy face going viral. Now, Grumpy Cat is holding court during SXSW at the Mashable House, a lounge run by the tech-news website.

According to CNN, people have been waiting in lines that snake around the block for hours just to get their picture taken with the cat.
