The Sims 2 Pet games has invited Hilary Duff and her Chihuahua Lola to guest star in the new game, which will be available in myriad formats.

“I love creating Sims characters and guiding them through life, designing their houses, and then blinging them out with cool furniture. Now, in The Sims 2 Pets, EA has combined two things I really enjoy – pets and The Sims”, said multi-platinum, chart-topping recording artist, actress, fashion designer, and philanthropist Hilary Duff.

On 20 October, The Sims 2 Pets will be released for Sony PS2 and Nintendo GameCube, and as a PC expansion pack for The Sims 2. A Nintendo DS version will appear at the end of October. Hilary Duff’s appearance will only last until 31 December.

The Sims 2 Pets will let players choose from existing cat and dog breeds and mixes, and also let them design them with the Create-a-Pet feature. Neglecting pets will have consequences such as a bored cat ripping up a sofa, and a dog digging up the flower beds.

In Sony’s PS2 and the Nintendo GameCube, Hilary Duff and Lola will visit the Town Center, where players may run in to her and interact with her.

In the Nintendo DS version, players will find her Central Park, while she will be a fully playeable character in the PC expansion pack.

Versions for Game Boy Advance and for the PSP will follow in November and December, with a mobile version rounding out the package in December.
