Nutritional management of feline chronic enteropathy

Abstract

Feline chronic enteropathy covers a heterogeneous range of conditions, including food responsive enteropathies, inflammatory bowel disease and antibiotic-responsive diarrhoea. Dietary management can be extremely helpful, both as a diagnostic and therapeutic tool, when managing many of these patients. A high proportion of cats with chronic enteropathy are thought to be either food-sensitive or food-responsive, and appropriate nutritional support can help to optimise the short- and longer-term management of gastrointestinal disease. Three key dietary options exist: highly digestible gastrointestinal diets, hydrolysed diets and novel protein diets. Highly digestible diets and help to reduce exposure to dietary antigens, minimise complications associated with undigested food and aid nutrient absorption. Novel protein diets, based on a protein source a cat has not previously eaten, or a hydrolysed diet, where protein sources have been reduced in size to below the molecular weight of most food allergens, can help support cats with an underlying food sensitivity (allergy or intolerance), and may also benefit individuals in cases where a true food sensitivity does not underlie the clinical signs. Improvements with appropriate dietary intervention can be dramatic and rapid, with resolution of clinical signs within 2 weeks. This article explores the rationale for each of the three types of diet that can be considered for a diet trial, and the current evidence supporting their use. It also briefly covers recommendations for diet introduction and advice to support clients when considering a diet trial.
