Hill's Science Diet Senior 11+ Indoor Dry Cat Food — digestive & immune support for mature indoor cats

Hill's Science Diet Senior 11+ Indoor dry cat food is a nutrient-balanced recipe designed to support digestion, immunity, and overall vitality in indoor cats aged 11 and older.

As cats age, their metabolism, activity level, and digestive needs change — especially for pets who spend most of their time indoors. Hill's Science Diet Senior 11+ Indoor combines easily digestible ingredients, targeted fibers, and antioxidant support to help maintain healthy digestion, lean muscle, and a glossy coat while addressing the common needs of mature indoor cats. The formula focuses on high-quality protein sources, omega-6 fatty acids, and a proprietary ActivBiome+ blend to support gut health and immune function, with no artificial colors, flavors, or preservatives.

How does this food support digestion and litter-box ease?

The recipe includes natural prebiotic fibers and easily digestible ingredients formulated to promote stable stool quality and gentler digestion in older cats. Consistent stool quality reduces litter-box mess and helps you monitor your cat's health more easily.

• ActivBiome+ prebiotic blend to support a balanced gut microbiome
• Natural fibers to encourage regular, firmer stools
• Digestible protein and carbs tailored for mature digestive systems

Will this recipe help maintain my cat’s muscle tone and weight?

Yes — the formula delivers high-quality protein to help preserve lean muscle mass as your cat ages, while balanced calories support healthy weight management for less active indoor cats. Controlled energy levels and nutrient balance are tuned for seniors who need steady, not excessive, calories.

• High-quality animal protein as a primary ingredient for muscle maintenance
• Calorie balance appropriate for lower activity indoor lifestyles
• Essential amino acids to support daily strength and mobility

What ingredients support skin, coat, and overall body health?

The food contains omega-6 fatty acids and vitamin E to nourish skin and promote a healthy coat, plus a mix of antioxidants to support overall cellular health. Ingredients are chosen for digestibility and nutrient density, and the formula avoids artificial additives.

• Omega-6 fatty acids plus vitamin E for skin and fur condition
• Clinically relevant antioxidants to support immune resilience
• Natural ingredients with added vitamins, minerals, and amino acids

Is this diet made to veterinary standards and what quality controls are used?
