Indonesia's president has ordered the beasts and other animals banned at street rallies..because:

The ban, issued Wednesday by Jakarta police, follows a demonstration last week in which protesters — who accused President Susilo Bambang Yudhoyono of failing to fight rampant corruption — tried to parade a water buffalo with Yudhoyono's name spray-painted on it through the city's main traffic circle.

Police removed the buffalo from the rally, one of a slew of protests held across the nation to mark the first 100 days of the president's second term.
