Nintendogs + Cats

As a pet simulator, this game is very good. It teaches kids how to be responsible pet owners. It is worth noting though, that the game works in real time and doesn't have a pause feature, unlike Tamagotchi. Thus, your child may spend more time on his or her 3DS than you would like because they have to take care of it on a regular schedule (2 times a day to feed and water it.)
