LONDON — What would you rather look at on your commute to work? Adverts for a variety of upcoming books, films, products and theatre productions?

Or just a hell of a lot of smiley cats?

Correctly guessing that most people would go with option two, the Citizens Advertising Takeover Service (CATs) crowdfunded a dream to replace as many London underground ads as possible with feline-themed photos.

Now, after raising £23,000 ($30,526) on Kickstarter, they've made that dream a reality.

On Monday morning, commuters going through Clapham Common station were greeted by the following sight:

The company behind CATs is a creative collective called Glimpse. They describe themselves on their site as "a group of friends who want to use creativity for good".

"We tried to imagine a world where public space made you feel good," Glimpse founder James Turner was quoted as saying in a press release sent to Mashable.

"We hope people will enjoy being in the station and maybe think a bit different about the world around them."

The cat photos will be up around the station for two weeks, should you wish to visit.
