The Sims 2: Pets

The Sims 2: Pets, or simply Pets, is the fourth expansion pack released for The Sims 2. This game was released on October 18, 2006 for US and Canada, October 20, 2006 for EU, and October 26, 2006 for Australia. The main idea of this game is to let you own pets. The PC verison is a remake of The Sims: Unleashed, which was a best-seller at that time.

On the PC, This game allows you to own pets such as dogs, cats, womrats (guinea pigs) and birds, although only dogs and cats are fully customizable in the Create-A-Pet screen. There were 72 premade breeds of dog and over 30 premade breeds of cats. Pets don't have the environmental motive; it is replaced by chewing for dogs and  scratching for cats. Sims can also sell pets with the Open for Business expansion. The game features Pet skills for pets. A new life state was introduced again in this EP: werewolf. To become a werewolf your Sim must have a daily and lifetime relation with a "Leader of the Pack" at least 50, and the wolf will "nibble" your Sims and he or she will become a werewolf. A werewolf will have change in skills and personality eventually, and have more interaction. One can turn another Sim into a werewolf by fighting with him or her. We also see the return of the Kat Family who've appeared in past pet expansions.
