A complete dry cat food formulated to help in the reduction of ingredient and nutrient intolerances in cats of all ages, including kittens.

This dry cat food is made with proteins that have been broken down (hydrolysed) into pieces that are too small to cause an allergic response. This makes it ideal for use in food tests that help identify food allergy.

Where to buy

Food allergy is an important cause of skin and gut problems in cats. Up to 30-50% of cats with chronic non-specific diarrhoea may also have either a food allergy or a food intolerance. The diet has a great taste thanks to high-quality ingredients and appetite booster.
