The Pack Leader is a wolf that appears in The Sims 2: Pets. He has dark fur and glowing yellow eyes. He comes onto residential lots like any other stray, but only at night (unless cheats are used). Like other strays, he will not appear in college sub-neighborhoods. Pack Leaders have various names.
If a high enough relationship is built between a Sim and the wolf, the wolf will 'nibble' the Sim and the Sim will become a werewolf. Unlike other stray pets, the pack leader can only be adopted with the use of cheats. If that is done, he will turn into a regular wolf.[confirmation needed]
