HA Hypoallergenic

What are the signs of food allergy?

Some cats may suffer from food allergies, which can cause skin signs (itching) and/or digestive upsets. These signs are not specific for food allergies so your vet will suggest various additional investigations to try to find out what is causing your cat's signs. The only reliable method of diagnosing your cat's food allergy is to carry out a diet trial using a diet specially formulated to avoid provoking an allergic reaction such as PURINA® PRO PLAN® VETERINARY DIETS Feline HA ST/OX Hypoallergenic.

This complete hypoallergenic veterinary diet helps nutritionally manage food allergies in cats of all ages, including kittens.

PURINA® PRO PLAN®VETERINARY DIETS Feline HA ST/OX Hypoallergenic is a true hypoallergenic diet formulated with protein that has been broken down (hydrolysed) into very tiny components that are too small to cause an allergic reaction , and a purified carbohydrate source.

Hydrolysed diets are recognised as the best type of food to use during an 'elimination diet trial' when trying to diagnose (or rule out) food allergy. During such a trial it is important that your cat is fed no other food or treats. PURINA® PRO PLAN® VETERINARY DIETS Feline HA ST/OX Hypoallergenic is also useful for cats with severe bowel conditions, such as Inflammatory Bowel Disease, as it is highly digestible.

This diet is available in a dry formulation of 1.3kg and 3.5kg
