Maine Coons, given their large size and active disposition, require a diet that supports both their energy levels and nutritional needs. A high-quality diet rich in protein is crucial to maintain their muscle mass and overall health. Due to their size, they may require more food than the average cat, but portion control is important to prevent obesity, especially if they are less active. Additionally, Maine Coons can benefit from diets that support joint health and coat quality, given their long fur and substantial body structure. Always ensure fresh water is available to support their hydration needs.
