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 with low molecular weight to help avoid allergic reactions.
  • Purified carbohydrate to reduce potential antigenicity of the diet.
  • High palatability thanks to high quality ingredients and hydrolysed digest (feline palatability booster).

15 Savannah hated this
Verified Purchase

By on 30 January 2021

Savannah wouldn't use it because it smelled horrible when it was on, and it didn't heat noticeably . Also, the crunchy sound scared her - she was fine with the Guy Fawkes fireworks in November. She wouldn't use it, so I binnned it.

We rescued two stray moggies around two years ago now . As soon as we brought them home the chronic diarrhoea began . We’ve spent an unimaginable amount of money on different tests and all came back clear . We tried various different vet prescribed diets and this was the last resort. We had solid stools within less than a week and we now have two very happy cats and two very happy owners . I was a bit concerned about feeding an all dry diet as they have had a mixture of wet and dry from they were kittens but recently ran out of this stuff and they wouldn’t even touch the old wet . Their bowls are never full for long . Thank you and top service from Viovet every time .

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

  • VioVet Staff

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.
