I saw a documentary on this species not too long ago. When they originally brought them into captivity they were vicious, but with selective breeding they ended up with friendly individuals that act similar to a dog. They kept a control group to that wasn't bred selectively to prove that it was their line breeding that has changed them, so the camera followed them into this control group and when the lady put her hand near the cage they would snarl and try to bite her through the cage. Comparing this to the selective bred foxes, she would put her hand near the cage and they would rush up to her and try to lick her through the cage, much like an excited puppy.
It's only a few generations of selective breeding that has got them this far. They already had individuals with colour mutations (fully white, etc.) and tail mutations (curly tail, extra puffy tail, etc.). I wonder how they will end up with the same extensive select breeding that our modern day dogs went through.
Either way I don't want to see them in Australia.
