Looks like people loves virtual pets, Nintendogs has sold over 250,000 copies only in the first week of sales in the U.S.

According to an official press release “Nearly 15 percent of all DS owners bought Nintendogs in just a week, a virtually unprecedented adoption rate for any title on an established system. And it’s also helping sell new DS hardware.”

Looks like Nintnedo has a winner with Nintendogs and i wouldn´t be surprised if they actually come up with Nintencats, Nintenfishes or something.
