The Cats vs Dogs Event began on December 3, 2010 and ended December 7, 2010. The reason for this mini-event is unknown, its resulting end brought a new achievements badge and a temporary 'Pets' discussion forum located in the Hot Topics forum. It is likely the event was created in response to a survey taken by Gaians, who wanted to see more events on the site, and also mini-events being a way to make use the Gaia Achievements feature.
