You can't... at least not yet. Try Sims 2 Pets for that.
simple.....YOU DON'T
At the moment you can't turn into a Werewolf but with Sims 3 Night Life you can be turned into a vampire!!but when the new Supernatural expansion pack comes out September 6th, you can become a werewolf, fairy, witch, and apparently a more 'scary' vampire.******* hope this helped!
You cannot have werewolves in The Sims 3 Pets, unless you have Supernatural installed in your computer as well.
You can't become a werewolf on The Sims 3 yet OK.
In the sims 3 pets your sim can be a werewolf.
No only in sims 2
No, you need The Sims 3 Supernatural expansion.
No, you can't.
There are 3 ways: - select the werewolf persona as a new character - receive the Werewolf Curse from an existing werewolf - create or buy the elixir called the Bottled Curse of the Lycan
In CAS select 'supernatural type' and change it to werewolf.
To easily and safely get werewolves on The Sims 3, you need to buy the Supernatural Expansion Pack.
On the Sims 3 for Wii, you cannot buy Expansion packs, so unfortunately you're unable to turn your sims into Vampires, or anything on the PC Expansion pack, Surpernatural (werewolf, zombie, wizard/witch, fairy, vampire, ghost) or the genie. Your Sim can turn into a Child, Teen, Adult, or Elder, so it can age up. Sorry!
