We warm up our cold patients in a cozy waterbed that we create with a litter box (big or small, depending on the size of the patient) and a heavy-duty trash bag. We place the litter box into the bag, add about 2 in of warm water to the litter box, and tie a knot in the trash bag. Then we lay a thin blanket, such as a receiving blanket, over the trash bag. This bed is great for young puppies and kittens as well as small patients recovering from anesthesia.
