728. Cooking for a Non-Jew on Yom Tov

98:35 All the activities that are permitted on yom tov are only permitted for the sake of people, not for animals. The Torah tells us (Exodus 12:16), “do for yourselves” – for yourselves but not for animals. Therefore, we may not cook or carry outside for the sake of an animal just like on Shabbos. (We may add to a pot of human food for animals – Rema 412:3.)

98:36
We may not cook or bake for a non-Jew on yom tov. One who has a non-Jewish servant may add food and cook it all in one pot so that there will also be enough for the servant. (He must not specify that he is adding for the servant – Mishnah Brurah 512:11.) For an honored non-Jew, however, one may not even add. (We are concerned that one will do extra for an honored guest – see MB 512:10.) Not only that, even if the Jew cooked or baked for himself, he may not invite a non-Jew to eat with him on yom tov. One may give a non-Jew who isn’t particularly distinguished something that he cooked or baked but he may not bake a loaf even for his non-Jewish servant. (For the purposes of this halacha, an apostate Jew is the same as a non-Jew – MB 512:2.)
