Hill'sPrescription Diet z/d Feline Low Sensitivity Dry Cat Food

Another approach to dietary management of IBD is hydrolyzed proteins, such as in Hill’s z/d, which contains chicken and rice proteins that have been broken down by hydrolysis into smaller particles. Theoretically, the molecules are too small to trigger an immune reaction, and thus the cat should never become allergic to this food. However, in practice, many animals have in fact developed allergies to even these foods, so long-term therapy with such foods is not advisable.

Hill's Prescription Diet® z/d® Feline Low Allergen is a complete and balanced food that provides all the nutrition cats need. 

Hill's® z/d® Feline is a complete and balanced food that provides all the nutrition your cat needs. Please consult your veterinarian for further information on how our foods can help your cat to continue to enjoy a happy and active life.

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 reactions to food, typically experience an abnormal response to the protein in the food. If your cat suffers from adverse reactions to food, it is even more important to feed the right food.

Hill's nutritionists and veterinarians developed z/d® clinical nutrition especially formulated to support your cat's skin and food sensitivities. In fact, z/d is clinically proven nutrition to help avoid adverse reactions to food.

My cat's health has declined since feeding him your "not" healthy food. I have already spent over $800.00 getting him better. I told my vet that I believe it to be the z/d diet. He said not to discontinue it after I went in for the 5 to 6 times. I asked for another vet and got very loud to fix my cat. I then took my cat completely off all the z/d and it's been at least a month and a half and is getting better each day!!! I will NEVER purchase your product ever again!!! Oh and I know about you guys previewing complaints and not posting them. So don't be deceiving or I will go further with my complaint!!! I do feel that Hills should reimburse me for all I had spent to get him better. I live check to check every week so this was a very heavy weight on my shoulders but my fur baby means the world to me and I feel like your product almost killed him.Unfortunately, the transition never worked out... Both cats began to have very loose stools and one cat began vomiting shortly after any attempt to eat. By the end of the transition period, both cats would sit at the food dish and cry for food, eat a few bites and walk away... Both still had very explosive loose stools tinged with blood and one cat was now also vomiting multiple times daily. After a few days of this, I called my vet who wanted to see the cat that had begun vomiting multiple times daily, right away. He received fluids, a b12 injection and an ultrasound. The doctor recommended that I discontinue feeding both cats this "improved formula" (which she was unaware of as well) immediately. My cats never ate another bite of the Hills "improved formula" prescription z/d, and have been thriving with zero incidents in the 7 months since I have transitioned them to a different diet.
