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 sensitive 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 reaction 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.

Key Benefits

  • Clinical nutrition especially formulated to help manage your cat's dietary sensitivity and help reduce the possibility of adverse reactions to food
  • Formulated with highly digestible carbohydrates and fats to help reduce gastrointestinal workload
  • Developed with increased omega 3 and 6 fatty acids to help nourish the skin and coat
  • No intact animal protein is included which helps avoid adverse reactions your cat might otherwise have
  • Added antioxidants to support a healthy immune system and skin barrier function

Special Note

Hill's Prescription Diets require a veterinary prescription. This product will not be shipped until a copy of a valid prescription authorization is faxed to 1-800-619-7973 or e-mailed to rx@chewy.com.

  • z/d versus d/d duck

    By on

    Previously, my cats were prescribed d/d duck food (they didn't like the venison version). Each of these foods have a noxious odor but, the z/d is substantially less intense. It also seems that they prefer eating this food, as they had typically taken almost two days to finish the previous type and they (2 cats) finish this can within (1) day, now (and, unfortunately, whine for one every night now).

  • Zero stars - stay away!

    By on

    Our cat has stomach problems, this was 3rd prescription diet we tried. After it failed big time, I donated the leftover to a friend whose cats are known to "eat a curbstone and get fat on it" - they would not touch it. Chose to prepare home-made food. Some extra work, but after 3 years of trying commercial products (of which this one was clearly the worst) the cat seems to be doing better.

    My 11 year old cat is now protein sensitive and our vet no longer carries this brand. Chewy.com was amazingly quick in sending a request to my vet to approve an order for this food! The order was shipped quickly and arrived in 3 days! Thanks for a great product and awesome service!

  • I hate it, kittens love it!

    By on

    Be warned. The consistency and smell are sicken. Do not open if you are already feeling nauseous. But I mash it up with water and my kitten that needs to be on it loves it. I didn't even need to mix the prior food. It has helped her digestive and allergy issues. My other kitten that does not need to be on the food (and who is so picky she won't eat the same food for two meals in a row) surprisingly loves it too and eats it every meal. They love the z/d dry food so much I had to get an anti-gulp bowl.

  • Love Chewy, not crazy about z/d can food

    By on

    The z/d can cat food is like a gel paste. I wish Hill's would change the consistency of this food. This is the only food my cat can eat without throwing up so I have no choice. Love Chewy and their customer service always!!

  • Just Hairballs now!

    By on

    Charlie ate too fast and puked. We bought the bowl with holes so he had to work for his dry food and it worked for a while. Then we changed to soft food. We even tried Zantac ... have you tried to give Zantac to a cat? The vet recommended this on a temporary trial. It worked. We only have hairballs now! Charlie will be on Hill Prescription Diet for life!

  • sensitive skin kitty loves it

    By on

    my cat has been skin flare-ups for the last couple years. my vet recommended him to eat hydrolyzed food to avoid any more flare-ups. it took a while for him to transition from his old food (he's picky!) but loves it now. it's kind of squishy, lol, but i mix it with some warm water to make a slurry, and eats it up. sometimes too fast and be barfs, the little stinker.

  • Chewy is a very good co. to work with.

    By on

    I was feeding my cat Natural balance Chicken & pea, excellent product found out our cat was alergic to chicken and duck so had to switch temperarily to z/d to find out this problem, called Chewy to get z/d and they gave me credit for the chicken and pea I just got, good business, I will of course continue buying from Chewy as soon as I find out what our cat can eat.

  • Still working on the diet change

    By on

    I have a cat that has always thrown up about 2-3 times a week on average. My vet would like her to be eating this only for 4 weeks to see if it helps. After a week of slowly mixing with her old food and getting to just this, after a couple days she stopped eating it. I'm trying one more time mixing with the old and slowly cutting back to see if I can get her to just eat this. So maybe I should have waited to write this but if I helps it'll be worth it. It is expensive and costs twice what I fed her previously which was Blue Freedom.

  • Worked miracles for my cat

    By on

    I've tried many different foods for my cat's allergies, and while some helped a bit, he still scratched his face and neck raw. This is finally the food that works for him. The scabs have fallen off and his fur has grown back. I am so happy!
