You learn something new every day, thank you. If Zeus hasn't had any issue with it so far, is it ok to continue to allow him to have some? "I dig for treasures" in his cat box daily (clean it), one of Zeus' favorite activities to help with. He thinks it's great fun to attack the scooper as I'm digging (how I digress, sorry). Where I'm going is he hasn't had any issue with milk at all.
