The Planet of Robot Cats has launched an attack to take over Dog-o-Tron and enslave all the dogs. If they succeed, they will outlaw fetch, tail-wagging, and dog parks. Not good.

You are Dog-o-Tron’s only hope. Head to DogShip Woof-10 and help avert a doggy disaster! All you do is click here, and start blasting away the sinister kitties. Watch out for the big one, and grab dog food whenever possible .

You don’t have to be a video game guru — or even be remotely good — to have a chance of winning. You just have to try. Here’s how it works:

Everyone who plays the game between February 17, 2010 and March 17, 2010 has a shot at winning a Nintendo DSi from Dogster! Each day that you play you will earn another entry to win – so the more days you play, the better your chances to win! Limit is one entry per day. Make sure you’re logged in to be entered. And may the Force be with you!
