Maybe another reason to dislike CA. The "first blood" regulation relies on the pursuit of animal. Part (a) states it's unlawful; to take, mutilate, or destroy game lawfully in possession of another.
Fish and Game Code 2011(b) a bird or mammal shall be deemed in possession when it is actually reduced to physical possession or when it is wounded or otherwise maimed and the person who wounded or maimed it is in hot pursuit.
Same basic law applies in ID, WY, and MT. You have to reduce it to possession, i.e. it's dead.
