As with every year at this time, I would like to announce that my monograph "Exotic Shofars - Halachic Aspects" is freely available. Each year I add some new material to it. This year's addition is to the section discussing a shofar made from a non-kosher animal. The halachic status of such a shofar is the subject of considerable discussion amongst Rishonim and Acharonim. But does this dispute have any practical relevance? Is there such thing as a shofar from a non-kosher animal?
