PURINA® PROPLAN® VETERINARY DIETS Feline HA St/Ox Hypoallergenic is a complete hypoallergenic veterinary diet for the diagnosis and management of food allergies in cats of all ages, including kittens.

Some cats may suffer from food allergy, which can cause skin discomfort and/or digestive upsets. PURINA® PROPLAN® 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. Such 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. PROPLAN® VETERINARY DIETS Feline HA St/Ox Hypoallergenic is also useful for cats with severe bowel disease such as IBD as it is highly digestible.

With St/Ox to help support urinary health in cats which may be susceptible to urinary conditions.

Key Benefits:

  • Single hydrolysed protein broken down into tiny components too small to cause an allergic reaction, 
  • Purified carbohydrates to help avoid allergic reactions
  • A great taste thanks to high quality ingredients and a palatability booster

Contents: 3.5kg bag


Fresh drinking water should always be available.

good value Barry White on 7 May 2020

My little rag doll cat has a very sensitive stomach and can only eat HA cat food. She is very happy with this particular dry food. Petplanet provided this at a competitive price and delivered it within an acceptable time frame.

finally found a hypoallergenic cat food that my 2 cats really love stella-dixon on 18 March 2020

have tried most of the hypoallergenic cat foods on the market. Found this one after much research and been using it for 2 years now.Sometimes they eat it in preference to their daily wet food. Customer service is also excellent

comparing the price with other sites this was the best value. good delivery time too. The product seems to work well for my 12 year old Persian cat who suffers from pancreatitis. He seems a lot more comfortable and now vomits very little. My vet wants his condition to now be managed through diet rather than constant meds if possible and so far this seems to be working. Will continue to buy from this site providing the price stays competitive.
