Specific FDD-HY Food Allergy Management is a complete, balanced hypoallergenic diet for cats which has a restricted number of ingredients to meet the nutritional requirements of adult cats with food allergies. This diet, based on rice and hydrolysed salmon protein, contains highly digestible ingredients and added electrolyte levels which make it ideal for those cats with gastrointestinal problems related to acute intestinal absorptive disorders, maldigestion and/or pancreas insufficiency. To avoid and symptoms of food allergy it is essential that the cat is fed only on a hypoallergenic diet.



  • Hydrolysed salmon protein - Hydrolysed salmon protein with a molecular weight < 10.000 Dalton has a high digestibility and a low allergenicity
  • Rice (Gluten free) - Rice has a low allergenicity and a high digestibility, which makes it a perfect ingredient in hypoallergenic diets. Rice does not contain gluten and will thus be tolerated by cats with gluten allergy/intolerance
  • High digestibility - Very high quality and highly digestible ingredients make the diet especially useful for patients with small intestinal diarrhoea
  • Healthy urinary tract support - A urine pH below 6.4 supports a healthy urinary tract
  • All ages - A complete, balanced diet with recommended nutrient levels to meet the nutrient requirement of growing and adult cats. The diet is therefore also suitable for kittens


  • Food allergy & intolerance - Lamb is a protein source with high biological value, and has a generally low allergenicity, which makes lamb perfect for a hypoallergenic diet.
  • High digestibility - Very high quality and highly digestible ingredients make the diet especially useful for patients with small intestinal diarrhoea.
  • Intestinal support - Psyllium Husk is a gel-forming soluble fibre, which absorbs several times its weight in liquid and is known for its beneficial effect on the regulation of the gastrointestinal tract activity.

55 Found a great product
Verified Purchase

By on 29 July 2021

After many bags of hills DD, ZD and Purina which my cat just wouldn't eat I've finally found this one which she eats happily. When dealing with a complex case of intestinal desease plus pancreatic insufficiency it's a daily struggle to get her to eat. After looking closely at the ingredients it it very high quality food and she is happy to eat. Sadly not marketed by UK vets who seem to stick to one brand .

I have tried many prescription foods for my cat with a delicate tummy. This Specific is one she wolfs down and has helped with her tummy issues- we aren’t fully there yet but luckily she likes it, unlike some we have tried!

35 Not keen unfortunately
Verified Purchase

My cat has developed what is suspected to be a food intolerance and I tried this to start an elimination diet. Unfortunately, she just wouldn't eat it and ended up losing a far bit of weight until I had to give up and try a different brand of food.
As a result, I can't comment on how successful it was in alleviating symptoms unfortunately.
The consistency of the food is like a fine pâté so if your pet already likes this kind of food, you may be more successful.

35 The cat is not a big fan ...
Verified Purchase

By on 3 May 2015

The cat will eat this if there is nothing else, i.e. she will eat the other cat's leftovers in preference (not so good for allergy management). Having said that it does seem to help in relieving symptoms.
