Pets also have their own needs and ambitions, which must be satisfied to keep life on an even keel. Cats must scratch while dogs love to dig and chew. Fail to provide a harmless outlet for these compulsions and your soft furnishings will suffer. Cats and small dogs can even climb on top of surfaces, perhaps to gobble up those leftovers that have been mouldering for three days.
Almost anything a human Sim can do, the Pets can follow – including careers. Dogs can join the police and rise to crime-busting Scooby status. Cats, naturally, can become supervillains and plot to take over the world. The Sims team claims that it’s entirely possible to play the game solely as an animal, forcing the Sims around you to cater to your needs, and that certainly seems plausible.
