Under what condition does a severed spinal cord covering render an animal trefe?
The animal is trefe only when the majority of the circumference is severed. A lengthwise split does not render it forbidden.
Question 2
What is the minimum length of a tear in the belly-covering flesh that renders an animal trefe?
The tear must be a handbreadth long. For a small animal, if the majority of the belly-covering flesh's length was torn it is trefe even if shorter.
Question 3
If thieves return stolen lambs to the corral out of fear of being caught, what is the ruling?
When thieves return animals out of fear, they are not careful, so we suspect the lambs' organs may have been crushed.
Question 4
An animal fell from a roof and afterwards walked on its own. What is the ruling?
Walking after a fall is adequate proof that the animal was not fatally injured.
Question 5
If an animal fell from a roof and did not stand up afterward, when may it be slaughtered?
It is forbidden to slaughter until a full day has passed. After a full day it may be slaughtered, but examination of all internal organs is still required.
