The potential stress of staying with your parents coupled with the dietary indiscretions and new food/treats may be the cause. As long as Rhea is behaving normally, you can try withholding all food and treats for 24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts. Begin with a couple tablespoons of food every hour and gradually increase the amount over the next couple of days. Feed a bland diet until the stool is normal then transition slowly to her regular diet. If the diarrhea does not resolve or if she develops lethargy, vomiting, loss of appetite or abdominal pain then have her examined by your veterinarian. A bland diet can be plain white rice mixed with one of the following: cottage cheese, cooked/drained ground turkey, cooked/drained ground beef or boiled boneless/skinless chicken breasts.
