Diarrhea can be caused by bacterial or viral infection, intestinal parasites, dietary indiscretions, overeating or even food allergies. Ideally, Chichi should be physically examined by your veterinarian to diagnose the underlying cause. A stool sample can be submitted to diagnose intestinal parasites or bacterial overgrowth. If Chichi is behaving normally otherwise, you can try withholding food for 24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts. Begin with 1 tablespoon of food every hour and gradually increase the amount. Feed bland until the stool is normal then transition slowly to the regular diet. Symptoms that should be addressed by your veterinarian include lethargy, vomiting, persistent diarrhea, loss of appetite or abdominal pain.

    I'm sorry to hear that Chance is not feeling well. Watery diarrhea can occur for a number of reasons including parasites, infections, dietary indiscretion and metabolic issues such as liver kidney disease. If Chance is very lethargic or if you are noticing blood in the stool, I would recommend that you have him seen by your veterinarian. They may recommend checking a stool sample for parasites. In cases of mild diarrhea, withholding food for 12 hours may be beneficial to rest the intestines. Water should be available at all times. After a 12-hour fast feeding small amounts of a bland diet such as boiled chicken and rice is recommended. If the diarrhea persists or if Chance develops any new signs, he needs to be seen by a veterinarian.

    Appa doesn't sound ok. She sounds sick. Feed her a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.
