The Sims 3: Pets is an adaptation of the PC game, but unlike that version, it's a stand-alone release and not an add-on for the original game. The gameplay is similar to the original, but for the PlayStation 3 version, it takes place in a new town called Sugar Maple Coast, exclusive to the console.
The focus of the game is the addition of pets for the sims to manage. It adds cats and dogs as new playable characters that the user can control, not including animals from other versions. Each pet can be customized much like human sims and have their own set of needs, traits, and personalities. A new mysteries system allows the user to complete quests around town to discover information about the history of the town.
Just like the console version, players have access to karma powers they can use to manipulate the sims and the environment. For the pets, it allows the user to transmogrify a pet to make it human, along with the ability to fill all need bars or introduce a disaster. Kinect support for the Xbox 360 version also allows the user to use voice commands to control certain aspects of the game.
