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.

Purina Proplan Hypoallergenic Cat food jkgla on 18 February 2024

My cat is allergic to storage mites (allied to dust mites) I feed her Pro Plan Hypoallergenic cat food + Whiskas Poultry wet food in sachets She really enjoys the Pro Plan cat food and is a happy, healthy puss.

Great Value. My cat loves it. Purrfect! moodybobtails on 16 October 2023

My cat had been on a much more expensive Brand for the last 8 years so I was a little apprehensive about changing his diet. I started giving him both brands for a while and he eventually chose Purina Pro Plan. This one is much lighter and better for his delicate digestive system.

One of our cats has recently been diagnosed with feline IBS and the vet recommended this . His condition has improved significantly, and he seems to enjoy it. Our other cat also rather likes it too, even though he has his own food! Arrived well packaged too.

Great value and perfect food for my cat who suffers allergies/intolerance to Certain foods. Since he has been on this feed, he has not had an issue. Anon on 7 August 2023

Price wise seems reasonable and delivery service very good.

Stopped my cat from vomiting Rach on 8 August 2022

My cat was ill regularly and losing weight due to sensible stomach. After a few visits to the vet, we gave him this new food to try. He doesn't throw up anymore and has started putting on some weight again. This is the one of the best values I can find too. Recommended!
