NOTE: This episode may be emotionally difficult, including the topic of still-births — animal and human (not together).

On the transfer of impurity from the carcass of a domesticated vs. non-domesticated animal, including that of a fetus. How does each category include the other categories (of domesticated including non-domesticated, pure including impure, etc.). With credit to Rabbi Yishmael and his methodology of learning these halakhot. Also, a new mishnah! On how the midwife becomes impure in removing the fetus. Plus, a question on how something that is fully enclosed and ritually impure can give off impurity, because it should not be able to. Nor to become impure. Plus, the question of impurity of food – as determined by whether it is fit for consumption by a dog.
