Quinn decides to buy a tiger cub off of the Internet. As the tiger cub "Sasha" grows, Quinn 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 Quinn is
grilling steaks for his friends, Sasha jumps on Quinn's guest Oscar and bites him as he tries to eat his steak. If Oscar sues Quinn,
what theory will he use to recover his damages?
