Tame Norway Rats descended from wild parents

These young Norway rats were found as pinkies living in a compost heap in Long Beach, California. We hand raised them, and they are tame, but we are pretty sure that their parents were originally wild (undomesticated) rats.
As you can see from their ears, tails, body shape and other features, they are clearly not Roof rats (rattus rattus) and, yet, their behaviour is similar to random, hand raised, rescued roof rat litters from wild parents (as opposed to Roofy or some of other selectively bred Roof rats.)
