Internet cat video festival is 'harder to get tickets to than Burning Man'

The viral videos have become an industry, now with their own gathering - and with that comes a 'cattoo' parlor, astrology readings and a sexed-up music video

When Joel Shepard started selling tickets for an internet cat video festival, he wasn't sure how much interest there would be beyond the cat fanatics (of which I am one).

Shepard, video curator at San Francisco's Yerba Buena Center for the Arts, was astonished when tickets sold out a month before the festival. And then came the emails.
