The treatment for animals that have mild diarrhea but are not dehydrated and sick generally involves withholding food for twenty-four hours, then feeding a low fat, bland diet such as boiled rice, potatoes, boiled lean hamburger or chicken, cottage cheese, or yogurt in small feedings for two to three days. In addition, commercial intestinal diets are available by prescription through a veterinarian. The diarrhea should resolve within a few days. Owners should never withhold water unless instructed to do so by the examining veterinarian.
If the diarrhea persists, the underlying problem must be treated in order for it to resolve. Oral or intravenous fluid therapy may be necessary to rehydrate the animal and prevent further dehydration. Antibiotics will treat any bacteria in the intestines. If parasites are present on a fecal floatation exam, de-worming medications should also be administered. In cats in particular, some causes of diarrhea may not be curable and may require lifelong medications to help normalize the feces.
