Description

SPECIFIC™ hydrolysed food allergen management is a complete dry food designed to help cats with food sensitivities and allergies. Contains a limited number of ingredients and hydrolysed proteins making it less likely to cause an allergic reaction. Hydrolysation cuts the protein molecules cut into very small pieces making them too small to trigger a reaction.

For cats of all ages with food allergies.

Why choose the hydrolysed Food Allergen Management?

  • Hydrolysed salmon and rice are ingredients less likely to trigger an allergic reaction.

  • Contains increased levels of Vitamin A, E and B complex and zinc and selenium to support and strengthen the skin, providing greater protection against environmental allergens.

Ingredients

  • Rice, rice protein, hydrolysed salmon protein (below 3,000 dalton), pork fat, minerals, powdered cellulose, vitamins and trace elements (including chelated trace elements), protein hydrolysate (below 10,000 dalton), fish oil, psyllium husk, taurine. With natural antioxidants (tocopherols, rosemary extract and vitamin C). Contains no added artificial colours or flavourings.

Expensive

By M H Martin on 26 July 2025

This is a good product but so expensive, I am sure it could be produced and sold for less.

Hydrlysed protein food
Verified Purchase

By Rosemary Morgan on 13 July 2022

Its a nice sized kibble with a pleasant odour. My cat thoroughly enjoyed a change from Hills Z/D diet for his bowel disease, but so did all the local cats too!

Q & A

Below are some recent questions we've received regarding SPECIFIC (Dechra) FDD-HY Food Allergy Management Cat Food, including answers from our team.

How much food?

Lesley Roberts

  • VioVet customer since 2025
  • From: Berkshire, United Kingdom

How do I know how much wet and dry combined? Both have guidelines but not if using both. 9 months old.

  • VioVet Staff

To combine both, you should aim to adjust the portions so the total daily intake is balanced. For example:

  • If your cat needs 1.5 cans of wet food per day, and you want to add dry food, you can reduce the wet food amount slightly (e.g., 1 can of wet food) and supplement with 25-30 grams of dry food. The total should still be in line with the recommended daily amount of food for your cat's size and activity level.

However, we would still advise consulting your vet.

Vet response contradicts product info.

Heather

Good morning

I noticed in Q&A section it states Specific XX food is not hydrolysed and has lamb as main ingredient (although slightly different code is used, but wondered if that was actually a typo), and that ONLY hydrolysed wet food on market is Hills ZD. However this product info states that the main ingredient is hydrolysed salmon and does come in both dry and wet food. So, is this Specific (VetXX) FDD-HY Food Allergy Management Cat Food suitable for cats who are on hypoallergenic, hydrolysed food?

Cat is currently on Purina hypoallergenic, but isn't very impressed as this only comes in dry and not wet version and he always had a mixture of both before. We have tried Hills ZD before too, but grey sludge consistency was not a winner with our cat. Vet has told us he must have hydrolysed food.

  • VioVet Staff

The wet version of Specific (VetXX) FDW-HY Food Allergy Management Cat Food contains lamb protein that is not hydrolysed, so it is unfortunately not a truly anallergenic diet. The only truly anallergenic hydrolysed protein wet food on the market is still Hills Z/D unfortunately.

Hydrolysed food

Sarah Ibberson

Hi my vet has advised we buy hydrolysed food for my cat, what if any wet foods are available please?

  • VioVet Staff

There are a few brands of hydrolysed anallergenic diets available. Specific FDD-HY dry is suitable, so is Purina HA, Hills Z/D and Royal Canin Anallergenic. It is advised to feed these as the only diet for 6 to 8 weeks once they are fully transitioned onto to determine if they are working or not.
The only hydrolysed wet diet available is Hills Z/D however currently there are supply issues with this. You can add some water to a dry diet if necessary to try and make an alternative wet version. Specific do have a Food Allergy Management wet food (FDW-HY) however it is not hydrolysed but has a novel protein source instead, lamb.

Hydrolysed protein

T Williams

Is the lamb in Specific (VetXX) FDD-HY Food Allergy Management WET Cat Food in the form of hydrolysed protein?

  • VioVet Staff

The lamb in the FDW wet food is not hydrolysed, it is a novel protein instead. If your cat has been recommended the FDD-HY but your vet then you should stick to this and only use the FDW if they advise this is appropriate.
