The Sims 2: Apartment Pets is a video game for the Nintendo DS. EA has described it as a follow-up to The Sims 2: Pets for the Nintendo DS. As in the original, it allows a diverse amount of customization, allowing pets to be created in a variety of colors and sizes.
The game begins with your Uncle Bill going on an expedition and leaving you to take care of the apartment. You can also take care of the pets already in the apartment of the beginning of the game. Soon after the game starts, the janitor will tell you about a lost puppy, and give it to you until the owner is found. This pet and more are ones that owners and various people will drop off, asking for you to take care of the pet for a few days.
