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. If your cat suffers from an adverse food reaction, it is even more important to feed the right food. Hill's nutritionists and veterinarians developed Prescription Diet z/d clinical nutrition especially formulated to reduce skin & digestive signs from food intolerances. In fact, z/d is clinically proven nutrition to help avoid adverse food reactions.

How it works:

  • With highly hydrolysed animal protein
  • With fish oil, increased levels of essential fatty acids & high levels of vitamin E
  • Proven blend of prebiotic fibres
