A cat kills a child. Is the cat subject to execution?
Halachah 1-2: Any animal, beast, or fowl that kills a human is sentenced to death by stoning — the Torah's 'ox' extends by Oral Tradition to all animals.
Question 2
The Torah says the owner of a mu'ad ox 'shall also be put to death.' What does this mean practically?
Halachah 3: The Oral Tradition interprets this as divine punishment — the owner is spiritually liable for death unless he pays the court-assessed atonement fine (kofer).
Question 3
Two partners own a mu'ad ox that kills a man. How much atonement fine does each owe?
Halachah 4: Each partner owes a full atonement fine independently — each requires complete atonement, so the fine is not split.
Question 4
A mu'ad ox kills a person inside the ox owner's domain. A person had called at the entrance and the owner said 'yes' (inviting entry). Is the owner liable?
Halachah 11: If the owner invited the person in (said 'yes' to the greeting), and the ox killed him inside the owner's domain, the owner is liable for the atonement fine.
Question 5
A person sets his dog on a colleague, and the dog kills him. Is the dog stoned?
Halachah 7: When a person sets an animal upon another person, the animal is not stoned — the action was directed by a human, removing the animal's independent culpability.
