Diners in Leederville's popular Oxford Street were left shocked and disturbed after vegan activists confronted them with disturbing animal cruelty vision and placards on Friday night.

The protest, organised by vegan activist group Direct Action Everywhere, saw several protesters march down the street holding signs and sharing grim details about how animals are slaughtered in abattoirs.

Footage of the protest captured by Nine News, shows one of the activists preaching to restaurant goers and urging them to watch an online documentary on animal cruelty as they try their best to ignore the protestors.

"Have you ever asked yourself, why do we love our pets yet dine on the lifeless corpses of other animals?" the activist yelled in the video.
