I doubt it very much. It would appear to be illegal:

No person may kill or attempt to injure a dangerous wild animal (African or Asiatic lion, tiger, leopard, cheetah, hyena, bear, elephant, wolf, or rhinoceros, or any subspecies or hybrid of these animals) that is held in captivity in this state or that is released from captivity in this state for the purpose of being killed, nor may any person conduct, promote, advertise, or assist in the hunting of a dangerous wild animal.
