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. PPVD HA 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. PPVD HA 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.

Pro Plan Veterinary Diets Feline HA Hypoallergenic Cat Food

  • 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.

45 Far more palatable than I expected.

I was not confident my cat would eat this as it's not meat as such. But not only did he eat it, but my other cat also did too.

55 The best hypoallergenic cat food.
Verified Purchase

By Elaine Farman on 5 July 2019

We have 5 cats who "graze" on dry food throughout the day rather than have set mealtimes. Edward, our 4 year old cat has a whole range of allergies (identified by a full set of blood tests). The only 2 foods that were a zero score for allergy were milk and eggs. Clearly, he couldn't survive on that! We bought every hypoallergenic cat food we could find (Science Plan, Royal Canin etc) and did a "taste test", this one won hands down. The others were left in the bowls whilst the bowl of Purina was licked clean. All of our cats eat this and they are all very fit and healthy. Edward's allergies extend beyond food so he is also currently on immunotherapy injections to try and desensitise him to some environmental allergies. With this in mind, the symptom of his allergies (in his case fur loss on his belly) was never going to disappear with just a change to a hypoallergenic diet, however, since the diet change, the severity of the fur loss has lessened and the occasional red spots and irritation have reduced in frequency.

This was recommended by my vet due to digestive problems with my cat after trying various makes. This is the only one my cat would eat. No digestive issues since.

Can you please give me a full list of ingredients. My cat is allergic to chicken in particular. Thank you.

  • Non-Executive Director

The ingredients are listed in the link towards the bottom of the listing on the website. There is no chicken or any other animal protein in this food. It is a specially processed diet which has all the protein sources partially digested already. This means that there are no proteins present at all (such as those found in chicken) and so it cannot trigger an allergic response. (Even if chicken was on the ingredient list, it should not matter because the protein is "hydrolysed" and so could not cause a reaction even to a dog allergic to chicken.)

It is quite an unusual looking diet with a very pale kibble, but dose work extremely well and is a very popular and effective diet for dogs with dietary allergies, whatever their cause.
