The Sims 3 Pets can then be inserted into a pre-existing Sims 3 home and become part of that household. The Pets can also multiply and have puppies or kittens! Players will be able to fully control and their immerse themselves into being a pet. Is kitty bored? Well they can go and scratch on that nice pricey sofa of yours. Sound familiar? Dogs in Sims Pets will even bark at objects that scare them. How is that for realistic.
