Royal Canin Health Indoor Cat Food is a specially formulated dry cat food for adult cats who have an indoor lifestyle, from 1 to 7 years old. Indoor adult cats tend to get less exercise than outdoor cats, that's why a balanced and complete diet containing beneficial nutrients is important for optimal health. Key Benefits: Stool & Odour Reduction - A lack of exercise may lead to a slower intestinal transit which can result in smelly stools. This nutrition helps to reduce stool odor with highly digestible proteins and precise fiber content. Moderate Calorie - Helps to maintain a healthy weight, due to a moderate fat content. Hairball Reduction - Specific fibres help to stimulate intestinal transit and eliminate ingested hair. Urinary Health - Contains a combination of minerals that help maintain your adult cat's urinary system.
