Royal Canin Indoor 7+ Senior Dry Cat Food: Comprehensive 4-in-1 Vitality Support for Aging Cats**

As your indoor cat reaches the age of seven, their nutritional requirements undergo a significant shift. While they may still seem youthful, the "early aging" phase—or **猫咪抗初老**—begins internally, affecting kidney function, joint flexibility, and metabolic efficiency. **Royal Canin Indoor 7+** (S27) is a scientifically formulated **全价猫粮** (complete and balanced food) designed specifically to meet the unique physiological needs of indoor cats entering their senior years.
