At age seven, a cat's nutritional needs start to change. She may need fewer calories to compensate for a slower metabolism, but protein may become more crucial than ever, to help maintain lean muscle mass.

Purina ONE Senior Protection Formula addresses the nutritional needs of the older adult cat. It provides antioxidant-rich nutrition to help fight the stresses of aging and help support joint health.

No Supplements Necessary. All Purina ONE diets are formulated to provide complete and balanced nutrition. Additional vitamins, minerals or other supplements are not required unless specified by a veterinarian.
