PURINA® PRO PLAN® VETERINARY DIETS Feline HA St/Ox Hypoallergenic is a complete hypoallergenic dietetic pet food for kittens and adult cats for the reduction of ingredient and nutrient intolerances, formulated with hydrolysed protein sources, selected carbohydrate sources and appropriate combination of the essential nutritional characteristics.

Some cats may suffer from food allergy, which can cause skin discomfort and/or digestive upsets. 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. 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. 


  • Single hydrolysed protein with low molecular weight to help avoid allergic reponses
  • Purified carbohydrates to help avoid allergic responses
  • A great taste thanks to high quality ingredients and appetite booster
  • With St/Ox to help support urinary health in cats which may be susceptible to urinary conditions
  • Useful for cats with severe bowel disease such as IBD as it is highly digestible

Contents: 3.5kg bag


Fresh drinking water should always be available.

Great results and great value Mrs M Steel on 13 March 2022

I was recommended this food for my elderly cat who developed a food allergy last summer, so far so good, stools are still soft but no diarrhea any more!! Will continue to feed her with this now, even the other cat eats it.

Great Product TK on 31 January 2022

Great product as the cat loves it, and good value for money too.

My cat loves it! Wolfie on 23 June 2021

My cat has a sensitive stomach and was frequently ill after eating supermarket cat food brands. We tried this under the recommendation of her vet and havent looked back. My cat loves the food and hasnt been ill, her fur is better and she is far more alert and playful. Recommend this product!

Fantastic Kevin Winter on 17 March 2021

Great product weve been using it for years now. My two cats love it.

Amazing! laura-h-baker on 26 January 2021

Weve been using this food for a year now after being recommended it by the vet. Weve tried various vet recommended foods in the past and natural foods but none were effective at all. 1 of our 2 cats has a very sensitive stomach and has been sick regularly for years and it was getting too much to cope with it. Amazingly both cats took to this food straight away which was amazing in itself as they can be very fussy. I think weve only had 2 sickness episodes in the last year which feels like a miracle after what we were dealing with before. It is also great value through this website compared to others as I did shop around before purchasing. Cant recommend this enough!
