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

Great Service
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.
Great Value
My 12 year old cat has both skin and intestinal issues. This food is the best I can locate for both ailments. He is happy to eat it, which was a problem with many of the other hydrolysed dry foods available.It definitely settles his insides and helps reduce his skin irritation.
My cat has severe colitis. Have tried every dried on the market and none have worked. Except this one. She has now put on weight, no incontinence, improved condition with fur. Amazing difference !!!
Good product.
This is a good product for cats with food allergies. I recommend it.
Unfortunately I had to ring tree times about not receiving my order and it was discovered after investigation it had gone missing however I did receive my order eventually after a week through another delivery company.
Excellent product

I ordered cat food due to a change in my cat's diet. I had no problems with the ordering process or with delivery which was very prompt. Because I ordered two large bags of food they were very good value. I will certainly use this site again because of the good service and competitive prices.
