Shabbat 143a and Shabbat 143b, finishing Notel with some discussion of muktzeh and nolad, when food not previously available becomes available, but only useful for animals, and the link between muktzeh and davar she-eino mitkaven. Havit starts with saving food, squeezing sponges, then shifts to a discussion of squeezing fruits and whether juice that oozes out on its own is prohibited or not.
