Since she is acting normally, she may be getting some food elsewhere.
If your veterinarian has not done so already request an appetite stimulant such as Periactin or Mirtazipine to give to her until you see her eating normally. You may have to try to force feed her. Try giving human baby food meats, or a variety of canned cat foods, or any foods that she may like.
You could also give your cat over the counter, Pepcid at 1/4 the human dose. If she is not drinking sub cutaneous fluid therapy may be necessary.
If she is doing everything normally except for eating, the pancreatitis may have resolved. To be sure that the pancreatitis has resolved, you would need to have her blood re-tested.
