There is a QTR somewhere about what you feed your animals -- part of it does state that they should be given foods that do not contain fillers that contain blood products... I too find this crazy, seeing the my cats eat just about anything live, as God intended them to do, and try to find packaged food that does not have something added.. it cost a bundle ...................
JESUS did not die for animals, he died for the humans, the blood decree, albeit, looked at improperly today, was directed toward the human population, not animals - animals do not have a hope of everlasting life if they put faith in Jesus' sacrifice...
