Full Answer

If an owner notices that his or her cat is experiencing an onslaught of diarrhea as well as frequent defecation, vomiting, black feces, weight loss and mucus substances in the feces, then the owner should bring the cat into its veterinarian as soon as possible. Without treatment, the problem can get worse and the cat can experience additional problems.

The diagnosis will be made after the veterinarian has had a chance to examine the cat and to run a stool sample. The veterinarian will be looking at tests that examine the digestive tract, the metabolic rate of the cat and whether or not any parasites or infections are present. He will also ask for a dietary history of the cat to look at the influence that food may be having on the cat's diarrhea problem. Treatment can involve a series of deworming treatments if there are parasites present, as well as antimicrobial drugs. Antibiotics may be prescribed as well as a new diet. If the diarrhea situation is severe then the cat may even be hospitalized so that it can begin receiving fluid and IV treatments.
