Adverts at Clapham Common station have been replaced with pictures of cats - to make commuters happier.
This campaign is the brainchild of the organisation Glimpse, who set up the crowdfunded Citizens Advertising Takeover Service (C.A.T.S).
The group raised £23,000 on Kickstarter to buy the advertising space in the station.
The organisation “hope it will help people think a bit differently about the world around them, and get inspired to change things for the better”.
The cats will appear on the advertising boards for two weeks.
