What Is IAMS Proactive Health Indoor Formula?
Introduction: Why Your Indoor Cat’s Diet Matters

Indoor cats are very different from outdoor cats. They move less, sleep more, and burn fewer calories every day. This makes them more likely to gain weight, develop hairballs, and face digestive problems. A regular cat food may not meet their specific needs. That is why a specialized formula like IAMS ProActive Health Indoor Weight & Hairball Care was created.
