She is doing this ad for Petadishoom, which is the Indian chapter for PeTA (People for the Ethical Treatment of Animals). PeTA has more than a million members and supporters and it is the largest animal rights organization in the world.
Founded in 1980, PETA is dedicated to establishing and protecting the rights of all animals. PETA operates under the simple principle that animals are not ours to eat, wear, experiment on, or use for entertainment.
According to a PETA release on 26 April, at Kolkata, Shilpa Shetty is reminding everyone who might be tempted to go to a circus that animals there are sorely abused, often inadequately fed, and routinely hit with whips and rods and even electric shock pods to make them obey commands for a few moments of unenlightened public amusement.
