The Sims 2: Pets is the fourth expansion pack in The Sims 2 series of games published by Electronic Arts. It was also sold as a stand-alone game for GameCube, PlayStation 2, Nintendo DS, Game Boy Advance, PlayStation Portable and Wii. Pets was announced on July 26, 2006, and released on October 18, 2006, in North American and via download, as well as on October 20, 2006, in European regions. It was released on October 26, 2006, in Australia.
It was released for the Wii on June 12, 2007, being the first The Sims title on the platform. In Australia, one Australian dollar per game sold, from at least 50,000 copies of the game, was donated to the RSPCA. Unlike the other expansions, this game does not have a new neighborhood. Instead, new lots (with Sims living in them) are available for placement in the existing neighborhoods. Pets has sold over 6 million copies. The console version differs from previous Sims console games, as there is no forced story mode for the player to accomplish, making gameplay more akin to the PC versions.
A sequel to Pets on Nintendo DS, The Sims 2: Apartment Pets, was released on August 26, 2008.
