How is she this morning??
The most important thing it to keep her hydrated. If you can, with aneyedropper, try giving her some apple juice or Pedialyte, which shouldre-hydrate her and stimulate her to drink more fluids. Just don't putthe eyedropper in her mouth, she may aspirate the fluid.
There was someone on the HamsterCare forum that's hamster had wet tailso severe the diarrhea was bloody. After getting him to drink somejuice and Pedialyte, he's eating, drinking, and active on his ownagain, and they expect him to make a full recovery.
