Never tried with water though.
Appropriately sized bags. A medium rat doesn't fit in a sandwich size, I buy three sizes: snack-sandwich-freezer.
The water gives more surface area to the rat where warming it on a heating pad is only by the rising air (convection). The bag alone will block some heat. You can maybe put it in a bowl of water and set that on the heating pad.
