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.

Hill's Prescription Diet z/d Original Skin/Food Sensitivities Canned Cat Food is rated 3.8 out of 5 by 107.
Rated 1 out of 5 by from "Improved Formula" is not improved My cat LOVED the original formula and it was just what she needed. She'd been having tummy issues for a long time and this was the first cat food that helped her that she liked. Once the formula changed though, she wouldn't touch it - at all. PLEASE bring the original formula back!

Rated 5 out of 5 by from Cat loved eating the old version of Z/D. My 14 year old cat has loved eating the older original Z/D formula for years. That formula is what I was ask to review as that is what I purchased from Chewy. Hills now has a new IMPROVED FORMULA and the amount of some of the ingredients has changed. Example-iodized salt has moved up to the 10th ingredient listed in the new formula compared with being about the 20th ingredient in the old formula. Some ingredients, calcium sulfate, cysteine, l-lysine, manganese sulfate and potassium citrate have been added. Sodium Selenite has been removed. Chewy now shows the IMPROVED FORMULA on its web site. That can has red on the label... the old can didn't. To help your cat avoid any possible digestive upset, it is best to gradually add more of the new food to the old food, for about a week, before totally feeding the new food all by itself. I think Hills recommends this also. I'll review the new formula later.

Rated 2 out of 5 by from NO to the "Improved" formula My cat has been dealing with suspected food allergies since February, after many months of agony and stress and many expensive vet visits we put her on the Z/D. She was doing quite well on it, it was controlling her scratching and licking and she was just in general more herself....until the new formula came out, I noticed almost immediately the itching and licking return. I called Hills to see what they changed and they said that they did not change any ingredients but added more fiber and anti oxidants....I am not happy. They also asked if I transitioned her to the new formula, how am I supposed to do that when just one day you show up to the pet store and there is a new formula with no warning that the old was going away?!!! Going to try a LID that has better ingredients to begin with :(

Rated 1 out of 5 by from The new z/d formulation is horrible. My cat has an autoimmune disease and was doing well on the old z/d formulation for over a year. He was switched to the new formulation without warning while being boarded because the old stock was used up. He came home with diarrhea and I noticed that the smell of the new formulation was horrible. Sort of like ammonia. I called Hill's right away and they calmly told me that there had been NO other reports of problems with the new formulation. They said only minor changes were made to the fiber and the antioxidants. They sent me 3 coupons. The new formulation smells and looks so different that my poor kitty doesn't want to eat it. We are now trying desperately to find another product that he can eat. Recently, I found out that the new z/d formulation is back ordered and I'm hoping they are changing it back to the old formulation. Please keep contacting Hill's!!!

Rated 3 out of 5 by from Helps, but cat doesn't like it much I bought this product for my cat, who has long-standing IBD. I don't like prescription diets, but since nothing else was helping him, I decided to try it. The first few cans I got from the vet were okay, other than looking like brown Jello, but at least my cat ate it. So I bought a case of the stuff from Chewy. The new stuff was marked "improved formula," which is arguable. It is slightly less gelatinous, but my cat doesn't like it as much. I think it's going to be hard to keep his weight up on this stuff since his appetite is rather poor anyway, despite being on an appetite stimulant. I do mix some of the dried Z/D in with it, which helps him accept it a little better. Can't really say whether I recommend it or not. Yes, because it does seem to lessen his symptoms of IBD, but no because it isn't very palatable. Some of the other cats don't seem to have a problem with it, so I guess you just have to try it and see how your cat reacts.

Rated 1 out of 5 by from Product needs work This food is not edible right out the can. You must mix it with water and ideally grind it in a grinder to make it palatable. Unfortunately it is the only hypoallergenic canned food available. I have to syringe it into my cat's mouth which he accepts . My cat was recently diagnosed with IBD and offering only dry food is not a reasonable option. However, mixing it with water does make it the consistency of a milk shake and easier to eat. Let's hope it helps his IBD issue.

Rated 2 out of 5 by from Was Recommended For Cat W/Pancreatitis GREAT for IBD cats due to the hydrolyzed protein aspect. HORRIBLE for Pancreatitis - they need LOW fat. Not sure why a Vet recommended this, however their prescription helped other IBD cats at the sanctuary I volunteer for. OLD formula = no idea, started when this new formula came out NEW formula = smells like death, weird gummy texture, not lickable, still has corn, difficult for most cats to eat, takes 30-40 minutes for a cat to eat 1/4 can.

Rated 3 out of 5 by from The New Improved Formula is not great My cat needs this for his allergies and it works. The new formula is like the paste kids used in kindergarten. It used to have a more pate texture but now its horrible. My cat tolerates it but I have to add water to thin the pastiness down. At this price I end having to throw a lot of it out as he wont eat all of it. I will be contacting Hills but Chewy is great!
