Check out this awesome preview of Pets by Platinum Simmers!
They showed us a Sims 3 Pets on console and PC presentation. Basically it was the same presentation we had seen at Gamescom. However two playthroughs in Sims 3 are never the same. If you want a general preview of Sims 3 Pets I suggest you go to: The Sims 3 Pets Preview (GamesCom)This preview will focus much more on minute details at the end of the article are long lists of pet traits, pet lifetime rewards, horse and dog breeds and the new Sim lifetime wishes.
If you have World Adventures, your pets can go with you on vacation. They cannot learn other skills there but can work on their usual skills.
Litters can consist of 1, 2 or 3 puppies/kittens/foals.
The new woohoo location is the Haystack.
There are no dog or cat flaps. Doors open for them like they would an ordinary Sim.
Can turn on/off free will for Pets.
Pet pregnancies are 3 days long.
Puppies, kittens and baby horses have no wishes.
