No wonder you are exhausted, you are putting everything in to trying to figure out what is happening for Sassy, and how to help her. I keep hoping she will improve and there will be an aswer for her behaviour and for the diarrhoea. Fingers crossed for the food, restarting the probiotic, and Prednisone along side the Pancur. Don't know what effect if any the Pancur might have for her diarrhoea...
