Oddly enough, Hanover is Purty Darn Shy but does require a Mousie-Cha-Cha ( ) performance before dining. I too use a plastic baggie and hot tap water, replaced once with more, to get the mousicle up to temp. However, either I buy cheap baggies or sandwich baggies are just too thin anyway, because if I use a sandwich baggie I end up with wet mouse and the snakes want a story of how I caught it for them and had to drag it through the river to bring it to them, so I skip storytime by using thicker bags like freezer bags, but I rinse and reuse them and keep them with the other husbandry supplies.
