Hill's Prescription Diet GI Biome Stress is a high-fiber dry cat food designed to support digestive health and balance the GI microbiome. The formula combines a proprietary blend of prebiotic fibers with clinically minded ingredients to promote regular stool patterns and may help manage everyday stress signals in some cats.
The diet features ActivBiome+ technology to rapidly activate beneficial gut bacteria and balance the GI microbiome, along with hydrolyzed casein and L-tryptophan to help respond to stress cues. A thoughtful blend of prebiotics supports calm, steady digestion, while omega-3 fatty acids (DHA & EPA) contribute to overall wellness.
Produced in the USA with globally sourced ingredients, the formulation was developed for GI care by Hill's nutritionists and veterinarians. It is designed to promote a urinary environment that may help reduce the risk of crystal formation. Always consult your veterinarian to ensure this diet is the right choice for your cat.
Note: This prescription diet is intended to support GI health and stress management in consultation with a veterinarian. If your cat requires GI care or experiences stress-related digestive changes, this diet may be one option your veterinarian considers.
