***Please Note: 3DS titles are not compatible with standard Nintendo DS consoles*** Nintendogs puppies are back in the palm of your hand on the Nintendo 3DS system, with even cuter and more expressive puppies and, for the first time, kittens! The fun from the original nintendogs game returns, with multiple breeds to choose from, accessories for your puppies and kittens to wear, and the ability to let your puppies and kittens train and compete in different challenges and activities. Nintendogs & Cats uses the built-in Nintendo 3DS camera and facial recognition technology to enable your puppies and kittens to react to your real-life movements, mimicking your head tilts and jumping up to lick you as you lean in.
