Food sensitivity and intolerance are potentially serious problems that can result in sensitive or 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. At Hill's, nutritionists and veterinarians have developed clinical nutrition especially formulated to help manage your cat's dietary sensitivity and help reduce the possibility of adverse reactions to food.

Rated 5 out of 5 by Both cats love it, & cat w/ with intestinal prob's is better I have two VERY finicky Burmese cats, one of whom has thickened intestinal walls indicating inflammatory bowel disease, which is very serious. It caused him to get increasingly sick, with diarrhea, frequent vomiting, weight loss, and his unhappiness indicated discomfort, too. The most common treatment for the condition is to feed the cat a prescription food such as this which has proteins that are already broken down into smaller bits that don't cause allergic reactions - and that's what Hill's z/d food is. Much to my surprise, my sick cat accepted this food very readily (likes it even better than his old kibble), and my second cat refused her old food in favor of this, so now it's the only food they eat. Too bad it's expensive compared to regular kibble, but it's still cheaper than the vet bills, and the sick cat is so much better! Both cats are at perfect weights, have shiny sleek coats and seem healthy & happy on this food, so I'm a big fan! August 17, 2016
Rated 5 out of 5 by My cat loves her food! My cat was put on this prescription food after nearly dying due to a bad case of hepatic lipidosis. Our vet recommended it because of worries my cat also had IBS that contributed to her declining health. Ever since she's been on this food, she's back to herself and has the softest, fluffiest coat. At 10 yrs old, the shelter we got her from said no one wanted to adopt such an old cat but now that she's been on this food, she's so happy and healthy, you would never tell she's 11 yrs old because she has so much energy! This food literally saved my cat's life. August 19, 2016
Rated 5 out of 5 by Z/D plus medication helped my cat with his skin allergies. When I had to change my cats diet from rabbit to Z/D, he was very happy with the dry food, but would not eat the wet. The consistency is almost like play dough, though I know cats who eat it without a problem. August 11, 2016
Rated 3 out of 5 by Stopped the vomiting, but produced diarrhea Our 3 cats were vomiting -- both freshly eaten food as well as just puddles of bile -- on their Blue Buffalo food. The vet presumed they had developed an allergy to it, so we switched them over to z/d. The vomiting stopped immediately! However, their stools are now so soft they're just puddles, and one cat has started leaving those outside the litter box for us to examine (how considerate). Their stools also contain mucus, which is not a happy thing. In addition to the loose stools, this food has also increased their shedding enormously. One cat who has never produced a hairball has now produced two in four weeks. While I'm sure it's great for them to not be allergic to their food, I don't know if these effects are any better.

Rated 4 out of 5 by A good choice for my persian I had to switch my persian to this diet because he was on the Royal Canine hypoallergenic diet earlier but he suddenly decided to stop liking it. I transitioned it in with the old diet and he eventually loved it. I only gave it 4 stars because the shape of the food is not Persian friendly. Persians normally don't chew their food and like to just swallow it so although he likes the taste, he has a hard time keeping it in his mouth. I wish the company would consider making a persian friendly version. The upside is that there is a wet version. Overall, I'm happy with the new diet. **I would also like to point out that I had already purchased a Royal Canine hypoallergenic dry food bag for my cat that I hadn't opened yet. Since my cat stopped eating that one completely, I ordered this diet for him prescribed by his Vet. Customer support at Chewy.com was kind enough to give me a full refund on the old unopened bag. 5 stars on customer service! May 4, 2016
Rated 5 out of 5 by Great product for cats with a sensitive stomach. Great product for cats who have extremely sensitive stomachs. Took my cat, Napolean, into the vet because he was vomiting at least once a day. I was at my wits end as I tried all sorts of things to help him and nothing worked. After running various test on Napolean and finding nothing medically wrong, My vet recommended trying Z/D Hills prescription Diet Skin/Food Sensitivities. Of course, at first, He wouldn't touch it. Then after two days he started eating it and now loves it. The best part is, no more vomiting. July 29, 2016
