Bava Kamma 23 - Shabbat November 25, 12 Kislev

Today's daf is sponsored by Ruthie, Ira, Elsa, Julianna, Reuben, Elia, Adele, Emanuel, and Arianne in honor of Elana Storch's birthday. "Mom/Savte, We so admire the example you set for all of us in your commitment to Talmud Torah. We love you. Happy birthday."  Rabbi Yochanan's approach that fire is like a person shooting arrows is questioned and it is explained that he holds that it is both like arrows and because it is owner's property. What then is the difference between Rabbi Yochanan and Reish Lakish? When a cow eats someone else's food and brings the food into its mouth, is it considered that it is now in the property of the cow (the one who is doing the damage) and therefore since it is eating (shen) and shen is exempt if it takes place not in the property of the one who is damaged, the owner of the cow is exempt or do we say that if the cow is standing in the property of the one who he is causing damage to, the cow's mouth is considered in the property of the one who is causing damage to and the owner would be liable? When does an animal become muad? What circumstances would need to happen for a muad to revert back to being a tam?
