Thanks for your response, Barbra.
Today Calley has eaten for the first time in three days w/o throwing up. Though it was just a little bit of food I am very happy she has kept it down for over an hour. She is still lethargic and not her usual self. I did not mention that I was out of town for four days, my neighbor came over and fed her. I wonder if that could have had anything to do with it. I am keeping my fingers crossed and if this continues I have decided to have an x-ray done.
