Your Sims have gone to college, opened their own businesses, and enjoyed their towns’ nightlife. Now let them add pets to their families with this new Sims 2 expansion pack. Adopt a pet through a service, buy one from a shop, befriend a stray, or even create your own dogs and cats from dozens of available breeds. Your pets possess their own personalities and can even get their own jobs, as well as breed with other animals. Sims who interact with a certain canine wandering through their neighborhood might become werewolves.
