Incidentally, you'll probably want to avoid doing just that in The Sims 2 Apartment Pets, a matching "apartment adventure" just for the Nintendo DS. The portable pet sim will task you with taking care of a variety of pets -- including "cats and dogs, slithery snakes, hamsters, colorful birds, and cuddly rabbits" -- and realizing that putting them all in the same room is probably not a great idea.
Both games are due on August 26 in North America and August 22 in European and Asia-Pacific regions. The Sims 2 Apartment Life will also be available in a Limited Collection, which includes The Sims 2 Double Deluxe ... and that would be The Sims 2, The Sims 2 Nightlife Expansion Pack, The Sims 2 Celebration Stuff and a DVD filled with "tips and tricks." Those should come in handy for defeating the final boss, Death.
