Two games in one bundle. The Sims 4 lets you build and customize Sims from personality to wardrobe, design homes, explore neighborhoods, and play out any kind of life you choose — the possibilities are genuinely open-ended. Cats and Dogs adds the ability to create and customize cats and dogs with distinct personalities and coats, experience their companionship through your Sims' lives, and build a veterinary clinic to pursue a career as the town's best animal doctor.
