Our review of Hill's Prescription Diet i/d Digestive Care Dry Cat Food finds it best suited for adult cats with sensitive stomachs or ongoing digestive issues; the single biggest reason to buy is its clinically targeted formula that helps settle digestive upsets and improve stool quality.

Key Features

• Clinically shown nutrition: Formulated to help settle digestive upsets and improve stool quality in adult cats based on clinical evidence.
• ActivBiome+ Digestion: A proprietary blend of prebiotic fibers designed to rapidly activate the gut microbiome and support digestive well-being.
• Highly digestible: The recipe supports easy nutrient absorption so cats get more of the nutrition they need even during digestive stress.
• Electrolytes and B vitamins: Added electrolytes and high levels of B vitamins help replace nutrients lost during episodes of digestive upset.
• Skin and immune support: Omega-3 and -6 fatty acids plus clinically proven antioxidants support healthy skin, luxurious fur, and immune health.
• Urinary health formulation: S+OXSHIELD helps promote a urinary environment that reduces the risk of struvite and calcium oxalate crystals.

Who It's For

This dry food is aimed at adult cats with chronic or occasional digestive sensitivity, including those recovering from upset stomachs or diagnosed conditions like irritable bowel disease when recommended by a veterinarian. Owners who want a veterinary diet with clinically backed ingredients and a focus on microbiome support will appreciate its targeted design.

It is not intended for kittens, pregnant or lactating cats, or healthy adult cats without digestive concerns unless directed by a veterinary professional.
