Hank decides to buy a tiger cub off of the Internet. As the tiger cub "Sasha" grows, Hank works with the tiger cub to ensure that it behaves properly when his friends come over, but occasionally Sasha resorts to her tiger instincts. One Saturday as Hank is grilling steaks for his friends, Sasha jumps on Hank's guest Joann and bites her as she tries to eat her steak. If Joann sues Hank, what theory will she use to recover her damages? Negligence per se. Danger invites rescue doctrine. Pure negligence. Res ipsa loquitur. Strict liability
