Hill's Prescription Diet z/d Feline Low Sensitivity Dry Cat Food, 8.5-lb bag

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.

Key Benefits

  • Formulated with Hill's Hydrolyzed Protein System, highly digestible proteins that minimize the chances of adverse reactions to food
  • A single, highly digestible carbohydrate source to help avoid adverse reactions to food
  • Highly digestible carbohydrates and fats to help reduce gastrointestinal workload
  • Increased omega 3 and 6 Fatty Acids to help nourish the skin
  • Added antioxidants to help maintain a healthy immune system and skin barrier function

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 786-528-6088 or e-mailed to

Hill's Prescription Diet z/d Feline Low Sensitivity Dry Cat Food Customer Reviews

Hill's Prescription Diet z/d Feline Low Sensitivity Dry Cat Food 4.7 5 35 35
Product keeps my cats healthy My cats, Toffee and Cocoa, are healthy, eat less, and do well with this product. February 28, 2015
So Far, So Good I can't tell yet if this works for our "allergy boy," but so far it is good. It's a bit pricy, but we'll bite the bullet on that if we know it works. February 25, 2015
worked for IBD but cat did not like My cat had lost a lot of weight and was frail by the time he was diagnosed with IBD. At first the cat ate this and started gaining weight. Over time we had to sprinkle probiotics to get him to eat. After about 2 months he wasn't eating much of this food and was wailing every time we cooked or ate. He normally is a very quite cat, so unfortunately we had to try another brand. February 14, 2015
Good pet food for cats with allergies My cats like this food. I feel good knowing they are eating a nutritious diet . My only complaint is the food smells awful and their poop even worse! February 13, 2015
This product is perfect! My cat has many allergies and is very particular about what she will and will not eat. She enjoys and often asks for more of the Hills Prescription Diet Z/D Formula dry cat food. The food is in small pellet form, making it easy to chew. February 13, 2015
Good service from I recently ordered pet food from this site and was VERY pleased at the service I received! I needed the food quickly and received quick and personal responses to my request. They treated me as though I already was a valued customer with my first order. I also received the product quickly. I have recommended this site to friends with pets and will continue to order my pet food and supplies from them. Thank you representatives! January 31, 2015
Used for years My cat has had stomach issues for years and been eating Z-D. I was getting it from my vet but the last two times I needed it they were out and only order once a month. When searching for other options, I found for about the same price. Very pleased so far. I've set up auto delivery so I shouldn't have any issues of running out again. January 17, 2015
Missy loves it! Missy really loves this cat food, and the best part about it is that she is getting healthier eating it. Her allergies are under control and she looks great. Thanks Hills Prescription Diets! December 27, 2014
every cat eats it One cat with food allergies and one without so we were relieved that both cats like this. November 26, 2014
fantastic product my cats allergy is gone........................... November 18, 2014
Helps my cat's allergies Managing my cat's allergens has been never ending. He's allergic to multiple things. Science diet definitely helps (I think I've tried every possible diets). The only reason I did not give it 5 stars is because my cat's stool stinks to high heaven on this food, but if it helps him not to lick himself bald....I'll deal with that. November 1, 2014
low allergen cat food dry My cat has allergies and itches. This keeps her skin and coat in good condition and she loves it. October 1, 2014
needed for skin problems We have two cats that have skin issues. One had success with this food over a year ago in clearing up his compulsive grooming disorder, and then could move on to non-prescription food. Since then we adopted another cat with allergies of unknown origin that result in skin rashes. We're hoping he'll do well also. They like the taste of the food, which is a good start! September 8, 2014
Good for my allergy-prone cats and all cats in the household! With 7 indoor cats in my family, I have been struggling with IBD, food, and environmental allergy issues among several of them. Z/D is one food they can all eat, and WILL all eat! Now, when they switch bowls - "the grass is always greener" in someone else's dish - they're all eating the same hypoallergenic diet, and the clinical signs have disappeared. September 4, 2014
Great product I usually get this cat food at the vets but when I went on line I found it on sale and got it. September 3, 2014
Hill's Diet z/d foods are great for my kitty. My Veterinarian prescribed the Hill's Prescription Diet z/d for my cat. My cat loves both the canned and dry varieties but I give him more canned than dry. His coat has regained its former luster, has lost a couple of pounds (as recommended by my vet). Great product, would recommend it to anyone! August 27, 2014
sadly my cat with allergies won't eat it My veterinarian recommended trying it for my cat with food allergies. Unfortunately she doesn't want to eat it. I appreciate having it available, but this one isn't working out for me. August 18, 2014
Best of the best! Love the Z/D crunch - my cat would rather have that then a canned food or a fish any day! July 26, 2014
the only food our allergic cats are able to eat. Several years ago our domestic shorthairs were having great difficulty digesting their dry food. They had skin rashes, granulomas, hair loss, and general crankiness. Our vet recommended Hills Rx Diet z/d for Felines and, lo and behold, the problem was solved. We also give the little fur balls Hills Hypoallergenic Cat Treats--which they love. Thanks Hill's Pet Diet products, and Chewy, which makes it easy to keep the larder stocked and save money! We're hooked. Ann, Marc, and the Girls July 24, 2014
She enjoys the taste! I haven't had my cat on this product long enough to know if it is making a difference but I do know that she likes the taste and her allergies don't seem to have gotten worse! June 30, 2014
Not too bad Recently my vet determined my cat Joe has food allergies so prescribed this food. Joe loves the dry but doesn't recognize the canned as being food at all. Unfortunately, the dry food gave him terrible diarrhea. I eventually switched him to Blue Buffalo Basic (limited ingredients), which seems to do the trick. But since Joe liked the Hill's Diet so much, I decided to try the dry food as a treat. This made Joe very happy and since he only gets small amounts of it there has been no recurrence of diarrhea. June 25, 2014
Works well for cats with allergies. My cat has food allergies and so far this is the only product that works for him. June 24, 2014
The first time I have used Chewy and their customer service department is awesome. Ran into a communication problem getting my cat's prescription sent to Chewy and their customer service stayed with it and kept me posted on the progress. Regarding the Prescription Z/D diet, my 17th year old cat, and the younger cat both, love it. My cat has a food allergy and would throw up his traditional cat food. He was always hungry and losing weight. Prescription Diet Z/D is a little pricey but my cat has been around 17 years and he will not be around forever. June 6, 2014
Best Price on! Excellent product for cat's with food allergies. My male Siamese has the food allergy, but my other cat eats the food as well. They both enjoy the taste. May 23, 2014
Expensive but working well for my cat. I had to try this food for my cat who was having problems with allergies. He's been doing well on it. There was an unexpected added bonus with my other cat who was also fed this product. He's always had issues with vomiting, but is rarely doing it now. January 6, 2014
Great food for cats with allergy issues We tried multiple types of cat food, but all made our cat ill, so finally went with a prescription. It took her a few days to get used to it (cats are not the most adaptable critters), but she enjoys it now and the best thing? It doesn't make her sick. January 5, 2014
Thank goodness for Z/D! My oldest cat has had a terrible time with food allergies and after being on D/D for a few years, started suddenly having awful skin reactions again which resulted in major scabbing, raw spots and hair loss. After a course of Atopica and switching her over to Z/D her allergies cleared up and she hasn't had any episodes since. Although my other cats have much more minor allergies they are on Z/D as well (which is really just to make life easier for me) and they are all very happy on it. January 5, 2014
