The stars came out Wednesday night at the state fairgrounds in Minnesota. The cat stars, to be exact.

Adoring fans turned out in droves to celebrate the second year of the Internet Cat Video Festival, hosted by the Walker Art Center at the Minnesota State Fair in Falcon Heights, Minn.

Fairgoers — many dressed in getups honoring their favorite cat celebrities — took in an hour-long reel of YouTube cat videos, including the debut of a new clip from Henri, Le Chat Noir. They also got to witness the first meeting of two formidable feline powerhouses: Lil Bub and Grumpy Cat.

Last summer's debut festival was such a hit, this year organizers had to move the event to the Minnesota State Fair's Grandstand in order to accommodate its expanding audience.

After screening an hour of cat videos, the second year of the festival came to a close with a bang: fireworks.
