On the May 1st, 2007 a group of young men entered one of McDonalds fast-foods in Moscow with a few dark bags. Nobody knew that in a few minutes they would take out of these bags a few cats and would start throwing these cats throughout the counter inside the McDonalds kitchen shouting "Free cashier". A few minutes later police arrived and arrested them together with a few cats as a clue for investigation.
This is the only photo from that event, it is not photoshop or something. People who participated in this didn't belong to any "no-meat-eaters" or "anti global corporations" movements, and indeed they were not from the "no-animal-cruelty" society. They are artists from an underground movement and have done it as the pure act of art.
