Any health care links located here are NOT to replace a veterinarian visit; please take your cat to a vet immediately at any sign of odd behavior or any symptoms of illness or injury. Call your vet and describe your cat's symptoms with any of your concerns about the cat's well-being. Your veterinarian may discover changes in your cat's health that you have overlooked. It is always better to err on the side of caution.

Feline Diarrhea

Diarrhea is not a disease; rather, it is a symptom of many different diseases. Many mild cases of diarrhea can be resolved quickly with simple treatments. Rarely, diarrhea is the result of a fatal illness, such as cancer. Even diarrhea caused by mild illnesses may result in death if treatment is not begun early enough to prevent severe fluid and nutrient losses.

Veterinarians attempt to classify each case of diarrhea as either a major problem or a minor problem and localize the source of the diarrhea to the small intestine or large intestine (or both). It is important to determine how long the diarrhea has been present and whether the cat has lost weight with the diarrhea. They use all of the information gathered to formulate a plan for diagnostic and therapeutic procedures.

Which cats are likely to get diarrhea?

Some potential risk factors for diarrhea include dietary indiscretion, exposure to cats with certain illnesses, a positive status for feline leukemia virus and feline immunodeficiency virus, and travel to areas of endemic fungal infection.

What are the clinical signs?

With minor causes of diarrhea, the cat may have no signs of illness other than the loose stool. Major causes of diarrhea result in the cat being visibly ill and exhibiting several, but usually not all, of the following:

Vomiting
Dehydration
Loss of appetite
Abdominal pain
High fever
Lethargy
Bloody and/or watery diarrhea

What are the possible causes?

Minor causes of diarrhea include:

Stomach or intestinal viruses
Intestinal parasites
Dietary indiscretions (i.e., eating garbage or other offensive or irritating materials)

Major causes of diarrhea may include:

Inflammatory bowel disease
Neoplasia
Fungal or bacterial infection
Hyperthyroidism
Loss of pancreatic function

How is the cause of diarrhea diagnosed?

If your cat does not exhibit the clinical signs of a major cause of diarrhea, veterinarians classify it as a minor cause. A minimum number of tests are performed to rule out common causes of minor diarrhea. These may include a physical examination, multiple fecal exams for parasites, and possibly an x-ray.

For cats who are visibly ill with diarrhea (major case), diagnostic procedures are usually implemented quickly. Veterinarians perform a series of tests that allow them to make a diagnosis so that specific treatment may be initiated. These tests may include tests for feline leukemia virus and feline immunodeficiency virus, radiography (x-rays) with or without barium, blood tests, stool cultures, biopsies of the intestinal tract, thyroid profiles, and exploratory abdominal surgery. Once a specific diagnosis is made, treatment may include special medications and/or diets, or surgery.

How is diarrhea treated?

With minor cases of diarrhea, treatment may be geared toward one or more of the common causes of uncomplicated diarrhea. Even with negative fecal examinations, many cats with uncomplicated diarrhea are routinely treated for worms. Other therapies often include drugs to control the motility of the intestinal tract, medications that relieve inflammation in the intestinal tract and, often a special diet for a few days. This approach allows the body's healing mechanisms to correct the problem.

With major causes of diarrhea, initial therapy may be supportive; this would include fluid replacement, electrolyte replacement, and perhaps antibiotics. Additional therapy will depend upon the diagnosis.

What is the prognosis?

With minor (uncomplicated) cases of diarrhea, improvement should occur within 2-4 days of initiating therapy. If this does not occur, a change in medication or additional testing may be needed to further define possible causes. Please keep your veterinarian informed of lack of expected improvement so that he/she may manage the situation properly.

Can it be transmitted to humans?

Some of the bacterial and parasitic causes of diarrhea are infectious to humans. If any members of your household are also experiencing diarrhea, it is important to let your veterinarian know. This will allow the veterinarian and physician to work together in managing potentially infectious causes of diarrhea.
