because they dont exist as a hunting species in the law you cant shoot them. farmer there hate them because they made a lot of crop damage and they attack walker too. of course, greens pet them!

greens pet also the wolf and when this guy will reach this area - whats only a question of short time -
this will end ... in a short time.
