Cats dominate email chains and triumph on Tumblr.

Without cats, where would the Internet be? A new—admittedly tongue-in-cheek—exhibition in London, For the LOL of Cats: Felines, Photography and the Web, invites visitors to respond to the phenomenon by sharing their own collections of cat snaps. Look for memes, photobombs, vintage shots, the cute, and the absurd. And be sure to LOL a bit at the idea.

On view at The Photographer's Gallery through January 6, 2013.
