Hill's Science Diet Adult 1–6 Indoor Dry Cat Food — Digestive Health & Lean Muscle Support

Hill's Science Diet Adult 1-6 Indoor is a dry cat food formulated to support indoor adult cats' digestion, lean muscle maintenance, healthy skin and fur, and balanced daily energy.

Designed for cats in their prime years, this recipe focuses on the nutritional needs of indoor lifestyles. It combines high-quality protein for muscle tone, natural fibers for gentle digestion and cleaner litterboxes, plus a targeted blend of prebiotic fibers and antioxidants called ActivBiome+ to help support digestive and immune health.

How does this formula support digestion and litter box cleanliness?

• High-quality, digestible ingredients for steady nutrient absorption

Will this food help my cat keep lean muscle and energy?
