Hill's Prescription Diet Gastrointestinal Biome is a veterinary-formulated wet cat food developed to support digestive health and promote regular, healthy stool. It requires a veterinary recommendation and is available in 82g cans.

The formula centres on Hill's ActivBiome+ ingredient technology, designed to activate and nourish the gut microbiome. It also delivers high levels of Omega-3 fatty acids alongside a targeted fibre blend. The canned format provides hydration alongside the nutritional support, which can be beneficial for cats with gastrointestinal sensitivities.

This is a condition-management food, not an everyday diet — it's suited to cats under veterinary care for chronic or recurring digestive issues. The 24-can case format suits ongoing dietary management rather than short-term use.
