Royal Canin Veterinary Hypoallergenic is a prescription dry food for adult cats with diagnosed food allergies or intolerances. It requires a veterinary recommendation and is formulated specifically to minimise adverse reactions to dietary ingredients.

The formula uses hydrolysed soy protein — broken down to a molecular size the immune system is less likely to recognise and react to — alongside a single purified carbohydrate source. This approach reduces the antigenic load that triggers skin irritation and digestive sensitivity. It also includes EPA and DHA to support skin barrier function in cats with allergy-related coat and skin changes.

Cats with confirmed food allergies often cycle through standard diets without resolution. This formula is designed for cases where a restricted, hydrolysed protein diet has been indicated by a vet — it's a clinical tool, not a general-purpose sensitive food.
