Two common bacteria involved in these cases are Staphylococcus and Escherishia coli (E. coli). Dehydration is the most serious side effect of diarrhea and vomiting. Infant animals can quickly go into shock from dehydration. Products such as Gatorade or Pedialyte are excellent for preventing this.

Chronic diarrhea is typically a symptom of an intestinal disease that has disrupted the lining of a cat's intestines. Infections that can cause diarrhea may come from a parasite, bacteria, fungus or even a virus.

Cancer, mal-absorption or mal-digestion disorders, inflammation of the bowels and diseases of major organs or systems of the body can also cause chronic diarrhea in cats. If we are going to use a trial and error approach I usually try metronidazole first but other vets like a different order. If it is successful I usually want to try sulfasalazine (Azulfidine Rx) when owners can readily give pills. If not, I might consider using injectable corticosteroids, usually methylprednisolone acetate (DepoMedrol Rx). In some cases, but not too often, we try to control the diarrhea using medications such as loperamide ( Immodium AD tm) or diphenoxylate (Lomotil Rx) for a few days.Chronic diarrhea is can negatively impact a cat's quality of life.
