What happens when you want Nintendogs + Cats but don't have a 3DS? You get this for $5 at GameStop.
It's not a horrible substitute, but it is a very one-trick pony type game, only focusing on the pet-caring aspect and BARELY having any minigames to play.
It's simple, but it suffices as a decent pet simulator akin to Nintendogs, even if it's unrealistic as all hell from someone who's owned several cats. Don't bathe your cats like they do in this game.
