Food sensitivity and intolerance are potentially serious problems that can result in irritated skin, coat and ear conditions or even gastrointestinal upset. Cats that have a food sensitivity or intolerance, also called adverse food reactions, typically experience an abnormal response to the protein in the food.

15 Changed formula

The formula has been changed and the new formula has fish oil which has triggered severe diarrhoea with blood in it. I have tried introducing it slowly but every time I do that the diarrhoea returns. I now have so much of this food left because my cat can't eat it. I am it's supposed to be hypoallergenic but it instead has fish which is one of the most common allergens.

The difference

Annette McDonald

  • VioVet customer since 2016
  • From: County Antrim, United Kingdom

What is the difference between the zd and the sensitive hills food as I ordered the sensitive food instead of the zd that my cat is on as he had allergies and the vet isn't sure what of all I no is that fleas are one

  • VioVet Staff

These two diets are completely different and are used in different situations. The z/d is processed so that it cannot contain any food allergens at all (theoretically). If there is a genuine concern about a dietary allergy, z/d is a good choice. The Sensitive diet is not free of allergens and might cause trouble if a cat happens to be allergic to one of the ingredients. The good thing about the Sensitive diet is that it is generally very easy to digest, so most cats will do well on it if they are prone to diarrhoea for other reasons. It would be fine to use in a cat with a flea allergy.
