Shabbat 155: Camels, Dogs, and Feeding Them

First, in memoriam: Rabbi Adin Steinsaltz, z"l. Then: how far can you to prepare food (for animals) on Shabbat? You cannot overfeed or force-feed animals on Shabbat (especially camels, and excepting chickens). Watering those birds that can't fly to get its own water is also acceptable. Tension between real world application of these laws vs. the true practices and concerns re forcefeeding. Plus: Feeding dogs. How long a food remains in a dog's stomach - but why? Could metaphors be afoot? (audio issues in the middle of this issue sort themselves out, and hopefully we have passed them fully, at least for the foreseeable future).
