One of the prescription Iams diets as well as the Innovative Veterinary Hi Factor diet emphasizes the addition of FOS to its formulation. Most carbohydrates are digested by the bacteria of the small intestine leaving only the undigested fibers and other dregs for the teeming masses of the large intestine. Tests in healthy cats indicate that this will help remove pathogenic bacteria from the large intestine and promote the growth of helpful bacteria. Think of it as an anti-crime program in the New York City of bacteria. Diets that contain FOS s may be helpful in the management of colitis.
Intolerances can result from dyes, preservatives, contaminants or even natural proteins in the food.
Similarly, colitis can result from an actual food allergy. The solution for these intolerances is the feeding a pure diet, ideally a home cooked food made with carbohydrates and proteins that are novel or new to the patient. An 8-10 week diet course is typically needed and no other chews or treats can be offered during the time of the trial. Food allergy cannot be diagnosed by blood test or skin test. Since itchy skin is a common manifestation of food allergy or intolerance, more detail on the subject of elmination diet can be obtained on the food allergy page.
