Those are domestic hooded rats, not wild at all.
It looks like your boys are coming along in the social arena, I bet they're loving having so much room to play! Have you given them anything to nest in? Burlap sack or an old purse works fine. After a while they'll start going to it when they get tired, and you know it's time to go back int he cage.
