Our Royal Canin Aging 12 Joint Health provides a moderate energy level to maintain an ideal weight. A Macro Nutrient Profile that is preferred by adult cats. The Macro Nutrient Profile (MNP) by Royal Canin is a new dimension of feline nutrition that provides long-term dietary satisfaction for cats. What is MNP? It is the redistribution of energy provided by each macro nutrient -- the optimal balance between proteins, fats and carbohydrates that supports long-term palatability. The specific Macro Nutrient Profile that a cat prefers varies according to its age, as well as physiological condition. Royal Canin canned wet formulas are designed around a cat's nutritional needs and instinctive preferences. By utilizing Macro Nutrient Profile science, Royal Canin has formulated this cat food to be instinctively preferred by adult cats. That means your cat gets a formula he or she loves while getting the precise nutrition he or she needs at each and every feeding.
