Skin and food sensitivities are extremely hard to manage without a change in diet. Even so, it is difficult to pinpoint exactly what your cat is getting an allergic reaction to. It can lead to a host of symptoms and issues that all stem from one problem - skin and food sensitivities.
Hill's Prescription Diet z/d Skin/Food Sensitivities Dry cat food is made to combat these issues with a unique formula that cuts down on any confusion regarding your cat's diet. This food is made with a single source of protein and a single source of carbohydrates. This way, you know what your cat is eating and lessen the risk of an adverse reaction.
The protein used in Hill's Prescription Diet cat food is hydrolyzed protein. The process of hydrolyzation breaks down the protein into amino acids with a low molecular weight. Hydrolyzed protein has a significantly reduced chance of being recognized as a protein by the body, and thus, your cat is likely to not react to the protein at all.
No, Hill's Prescription Diet cat food doesn't contain any soy protein. This food is also made without any lactose, as that is a common allergen in cats and dogs. The diet is a highly palatable kibble, and most cats enjoy the taste. And since your cat is likely to not get any allergic reaction from this, this food is more likely to be accepted by your cat.
To ensure that your cat is at the least risk of triggering an allergic reaction, Hill's hydrolyzed protein cat food is also made entirely without artificial colors or flavors. Synthetic dyes and flavors can trigger reactions and are often overlooked as sources of allergens.
Food and skin sensitivities often leave cats with recurrent infections that deal a blow to their immunity. Hill's hydrolyzed protein cat food also contains a blend of vitamins and minerals that boost your cat's overall health and immunity as well.
One of the symptoms of food sensitivities is gastrointestinal distress. Your cat can lose their appetite, feel nauseous, and feel discomfort after eating food. Many cats lose their appetite because their regular food is making them feel sick.
When you put your cat on Hill's single protein cat food, these symptoms will be reduced, and you might notice an increase in appetite! This cat food is also made with a healthy amount of natural fiber, essential fatty acids, and lots of vitamin E.
The fiber in Hill's hydrolyzed protein cat food helps minimize the gastrointestinal distress that cats with food sensitivities often face. The essential fatty acids and vitamin E help repair and fortify the skin barrier and nourish the skin and coat.
If your cat has been facing skin issues like rashes and coat issues like a dull or thinning coat, these ingredients will help reverse the damage done.
The general guidelines for feeding your cat Hill's Prescription Diet cat food is as follows:
These amounts are given in grams as grams are a more accurate measurement. Please note that these amounts are to be given daily. You should not give these amounts twice a day as you will risk your cat developing obesity.
You should also make sure you transition your cat to this food over at least a week. Standard protocol is to start substituting Hill's hydrolyzed protein cat food for 25% of your cat's meal at first. Then, increase in 25% increments over the next few days. Please be patient and take as long as your cat needs to adjust to this new food.
Hill's Prescription Diet z/d Skin/Food Sensitivities Dry cat food is a nutritionally complete and safe cat food. There are no side effects of eating this cat food. However, you should check if your cat is allergic to any ingredients whenever you give your cat food. If your cat is allergic is something in the ingredients list, speak to your vet.
Both Science Diet and Prescription Diet are specialized pet food brands developed by Hill's Pet Nutrition. Pet foods belonging to Hill's Science Diet brand are formulated to fulfill the nutritional requirements of healthy pets during various stages of their life. You can procure Hill's Science Diet pet food through a licensed veterinarian, as well as at pet specialty stores and grooming facilities.
On the other hand, Hill's Prescription Diet brand pet foods are formulated to address the nutritional needs of pets with specific medical conditions, such as food sensitivities and allergies. For instance, Hill's Prescription Diet z/d Skin/Food Sensitivities Dry Cat Food is made using hydrolyzed proteins to prevent food allergies and ease digestion.
Unlike Hill's Science Diet, Prescription Diet brand pet foods are only available through licensed veterinarians.
The best way to tell whether your cat is prone to skin and food sensitivities is to keep an eye out for symptoms of food allergy and intolerance. Common symptoms of food allergies in cats include:
Hill's z/d Cat Food is formulated to prevent feline food allergies. Being a hypoallergenic food, it's composed of a single carbohydrate source and a single protein source. That helps you easily determine whether your cat's food is triggering an allergic reaction. Also, it's formulated to eliminate food-related causes of skin and gastrointestinal issues.
Unlike traditional dry cat food, Hill's Prescription Diet z/d Cat Food contains hydrolyzed proteins. These are smaller, low molecular weight peptides obtained by breaking longer chains in amino acids. It makes hydrolyzed proteins better suited for passing through your cat's body without being detected by the immune system.
Also, Hill's Cat Food contains essential minerals and vitamins that strengthen your cat's immunity and overall health. It's made using completely natural flavors and colors to further eliminate the risk of allergies. Also, it prevents skin irritation and promotes a healthy skin barrier.
Hill's Science Diet is developed based on research conducted by veterinarians, pet nutritionists, and other professionals. Its scientific formulation provides biology-based nutrition to cats of different age groups. All the ingredients are carefully sourced and tested to ensure that they're safe for consumption. Nevertheless, it's a good idea to consult your vet before introducing your cat to Hill's Science Diet.
The most common food allergies in cats are caused by beef, fish, and dairy products. Artificial colors and flavors present in dry cat food can also trigger allergic reactions. Watch out for signs of skin irritation/inflammation and gastrointestinal distress to understand whether your cat has food sensitivities.
Food allergies in cats are difficult to diagnose due to the absence of proper tests. Also, the symptoms of food allergy often overlap with those of other medical conditions. While it's essential to watch out for nausea, vomiting, skin inflammation, and other signs of an allergic reaction, you must consult a vet. Once they rule out other medical disorders, the vet will put your cat on an elimination diet to identify the specific foods that trigger it to identify the ingredients that trigger his allergies.
The most common symptoms of food allergy in cats are:
You should, however, watch out for other signs, such as recurring ear infections and respiratory problems.
Treatment of feline allergic dermatitis depends on its underlying cause. While anti-inflammatory drugs, such as corticosteroids, and antihistamines alleviate the symptoms, they don't provide a permanent cure. The best approach is to consult your vet and let them identify the root cause of the allergy.
Cats are inherently meat eaters, which means they need protein from meat for proper physical development and immunity. From beef and chicken to turkey and deli meats - you can feed different types of cooked meat to your cat. Raw meat, however, is a strict no-no because it contains harmful bacteria and could be difficult to digest.
Gastrointestinal symptoms of food allergy start improving within 2 to 4 of starting a veterinarian-prescribed diet and treatment. Skin irritation and coat will take longer to improve. If you're trying a new diet to treat your cat's food allergy, you'll need to wait for at least 12 weeks before you can determine whether it's working.
If your cat has food sensitivities, you need to find a suitable diet that avoids the ingredients causing the sensitivities. Limited Ingredient Diet (LID) cat foods typically contain a limited number of ingredients to minimize the risk of triggering sensitivities. Look for products that feature novel protein sources (such as duck, rabbit, or venison) and alternative carbohydrate sources (such as sweet potatoes or peas). Some cats may have sensitivities to grains like wheat, corn, or soy. Grain-free cat foods replace these grains with alternative carbohydrate sources like potatoes, peas, or tapioca. Hydrolyzed Protein Diets have proteins that are broken down into smaller molecules, making them less likely to trigger an immune response. Hydrolyzed protein cat foods are often prescribed by veterinarians for cats with severe food allergies. Preparing homemade meals also allows you to have complete control over the ingredients. Consult with a veterinary nutritionist to ensure the diet meets your cat's nutritional needs and avoids specific allergens.
Yes, cats can be sensitive to dry food. Some cats may develop sensitivities or allergies to specific ingredients commonly found in dry cat food. These sensitivities can manifest as digestive issues, skin problems, or other allergic reactions. Dry cat food often contains a variety of ingredients, including grains, meat by-products, fillers, and artificial additives. Some cats may have sensitivities to certain grains like wheat or corn, while others may be sensitive to specific proteins or additives. If you suspect that your cat is sensitive to dry food, you can try switching to a different brand or formulation that uses different ingredients. Look for cat foods labeled as "limited ingredient," "grain-free," or "hypoallergenic," as they may be more suitable for cats with food sensitivities. However, not all cats will have sensitivities to dry food. Many cats can thrive on a well-balanced dry food diet.
Cats can develop sensitivities to certain proteins, especially those commonly used in cat food such as chicken, beef, fish, or dairy products. Protein allergies can cause symptoms such as gastrointestinal upset, skin issues, or itching. While cats are obligate carnivores and do not require grains in their diet, some individuals may have sensitivities to grains like wheat, corn, or soy. Grain allergies can lead to digestive disturbances, skin problems, or allergic reactions. Despite the popular image of cats and milk, many adult cats are lactose intolerant. Consuming dairy products can lead to digestive upset, including diarrhea and vomiting. Some cats may be sensitive to artificial additives such as food colorings, preservatives (like BHA or BHT), or artificial flavors. These additives can cause gastrointestinal issues or allergic reactions. Cats with sensitive stomachs may have trouble digesting certain fillers or by-products commonly used in cat food, such as corn gluten meal or meat by-products. These ingredients can contribute to digestive problems or food sensitivities.
When treating food intolerance in cats, the primary approach involves identifying and eliminating the specific ingredient(s) causing the intolerance. Consult with your veterinarian to discuss your cat's symptoms and concerns. They can help determine if food intolerance is the underlying issue and guide you through the treatment process. An elimination diet involves feeding your cat a novel protein and carbohydrate source that they have not been exposed to before. This can be a commercial hypoallergenic diet or a homemade diet recommended by a veterinary nutritionist. The goal is to identify and eliminate the specific ingredient(s) causing the intolerance. During the elimination diet, strictly avoid all other foods, treats, and supplements. Feed your cat the elimination diet exclusively for about 8-12 weeks. During this period, closely monitor your cat's symptoms to see if they improve. If the symptoms disappear or significantly reduce, it suggests that the previous diet contained an ingredient causing the intolerance. After the trial period, you can begin reintroducing individual ingredients, one at a time, to identify the specific trigger(s). Start with small amounts of the suspected ingredient and closely monitor your cat's response. If symptoms reoccur, it indicates an intolerance to that ingredient. Once the trigger ingredient(s) are identified, you can create a long-term diet plan that avoids those ingredients. This may involve feeding commercial hypoallergenic diets, limited ingredient diets, or homemade diets with the guidance of a veterinary nutritionist. Ensure that the diet meets your cat's nutritional requirements.
When selecting a dry food for cats with allergies, look for options that are formulated to be hypoallergenic or limited ingredient diets. Royal Canin Veterinary Diet Selected Protein Adult PD dry cat food features a limited number of carefully selected proteins and carbohydrates to minimize the risk of triggering allergies. It is designed for cats with food sensitivities and provides complete and balanced nutrition. Hill's Prescription Diet z/d Original Skin/Food Sensitivities Dry Cat Food is formulated with hydrolyzed proteins, which are broken down into smaller molecules to reduce the chance of an allergic response.

My Maine Coon had surgery 5 weeks ago, which resulted in him needing to be in a cone and having to be contained so he wouldn't jump or get debris in his surgical incisions. I kept him inside of a roomy multi-tier cage to ensure his safety. He was just fine until I had to put him in a longer cone, as the cone my vet gave us was too short and he was still able to reach his wounds through it if he tried. He became very depressed in the longer cone and started having liquid diarrhea. We went to the vet and tried metronidazole and Royal Canin Gastrointestinal dry food to little avail, even after removing the cone. He started vomiting last week and I had to give him Cerenia. The vet mentioned that Hills z/d dry food might work to stop his GI issues since the GI food didn't. Within a day of feeding z/d, my cat has completely stopped being sick and now has the same perfectly solid, firm stools he used to have before he got sick. I am hoping I can wean him off of this food later since I believe his GI issues to be stress induced, and not true food sensitivity.
When I first got this for my cat, he loved it (the dry, not the wet), but now that's he's been on it for about a year, he refuses to eat it. He takes a sniff, then walks away. He's lost quite a bit of weight, so I've had to supplement his diet with the Hill's Sensitive Stomach wet food (the regular kind, not the z/d. Neither of my cats will eat the wet z/d). I wish Hill's would make this in another flavor.
My senior cat has an extremely sensitive stomach AND he's incredibly picky. So what a relief that he likes this food, and it doesn't upset his stomach. I will say that the kibble is bigger than other brands, and with a lot of his teeth pulled out, he has a hard time chewing it.
My senior cat loves this food, and it doesn't make him sick. The only negative is that the kibble size is too thick, making it difficult for him to eat. Wish it were thinner.
She did not like the canned version of this, but she does like the dry version. She is no longer throwing up and has normal stools. I read that dry food is hard on a cat's digestive system and they can get pancreatitis from it, so I pour some water over it to soften it up for her. For her pancreatitis I am also mixing in probiotic and curcumin with pepper.
Our cat eats this, however, after a couple months, he is looking at it, "again? the same old same!" It would be very nice to have some variety in flavors for the feline to enjoy since all else has been eliminated from his diet :( But Thank you for having an affordable food for our paw family member!!!
My poor kitty had food allergies that make all other foods even the organic and pure meat varieties indigestible. Plus she's usually very finicky about flavors. However, this food works for her and I'm so grateful! Also PetCareRx gives the best prices and easy ordering with my vet. Thank you!
My cat loves this food as well as the z/d wet food. Not only does he love it but he has no more itchy skin!! You definitely need some patience this wont happen right away and it will seem like it isn't helping at all and then one day they just stop itching. He never had a problem eating either of the foods. I buy the food through my local APL so I haven't had any issues with the dry food being out of stock but the wet food has been out of stock at my APL for a month or so now. Overall my cat loves his food and his skin and fur looks better than ever !!
Our two Savannah cats James Bond and Natasha started having some serious vomiting and diarrhea issues about 2 years ago. Our WONDERFUL Vet diagnosed them with IBD and started them on daily prednisolone which worked like magic! They did have some breakthrough symptoms, albeit rare, so she recommended we start them on the Hills z/d formula. Since starting the z/d we have had NO symptoms whatsoever. I highly recommend using Hills z/d formula if you are experiencing issues such as ours.
Can't find this anywhere in Australia. Been trying to find it for months now as it's my cat's main food for years. He has been sick since we haven't been able to give it to him. There must be lots of owners of cats n this situation. Very upset as nobody including Hills can give me a straight answer when this will be available again.
My cat was throwing up several times a day. Switched to this food and he hasn’t thrown up since. He has been on it for 5 years. It’s expensive but it beats cleaning up cat vomit multiple times per day. And he is healthier and his fur is silky. Definitely recommend if your cat is having digestive issues
My cat loves this
My cat is 18 years old and has had diarrhea along with some vomiting. You could actually hear his belly rumbling when sitting next to him. We just went thru our first bag and he loves it!!!! I have other cats so I thought it was going to bd really tough, but he doesn't even want his old food!! He cries when he's hungry. He's doing FABULOUS!!!! Definitely would recommend! His stools are also back to normal, and no more vomiting!!!!
My cat was prescribed this due to ongoing vomiting and diarrhoea. Changed from the indoor kibble. But this product has made my cats stool almost liquid and upset before toileting.
My cat is 10 years old & was prescribed this by our vet. It did wonders for her as she often brought up her food but hasn't for a long time now. However, in the last month this formula must have changed as she's constantly washing herself & has become a bit feisty. Very disappointed and will now need to go back to my vet & change her diet.
Sadly new formula has seen a backwards step in our cat's health. Has been on z/d for years after chronic gut issues. Now worse than ever diarrhoea since the "new formula" Attempting to find another food that our kitty can survive on. Sorry Hills - you guys have messed this one up
My cat was eating ZD for about 5 years after suffering allergies to most meat, since the new formula we have seen skin allergies return and she's starting vomiting her food up. Why did you change the formula?
Our cats have been on Z/d for years. The Burmese because she was pulling her fur out and the Australian Mist for vomiting. Now that the formula has changed, the Burmese is once again pulling her fur out and the Mist is back to vomiting. If it ain't broke, don't fix it. We will need to try something else now.
My 10 year old cat would vomit right after eating. 2 vets & finally a new vet recommended Hills zd. A little expensive but it's so worth it as my cat stopped vomiting immediately. She has gained 4 lbs wish they could make it in lower fat diet.
Both of my cats were doing well on the old formulation, however, Hill's changed the formula and kibble size. Now both of my cats are having allergic reactions. Sadly this was one of the few foods I could feed them and did for years. Pops (my male cat has pancreatitis) and Missy was a stray who lost all her teeth prior to my adopting her was able to eat the tiny kibble but the larger units are too big for her to swallow. Both did so well on the old formula, I really wished they kept the old formulation for cats unable to eat and/or digest this food.
My cat was on this food for almost 2 years when they changed the formula he got the runs and has been sick ever since. Ive been taking him to vets changing his food now im back to square one. This is terriable for them to change it when he was doing great on it.
My 14 yo kitty has had so many issues most recently a severely inflamed pancreas. She was losing too much weight because she couldn't keep it down and stopped eating dry food all together. She LOVES this and so does my other kitty. The pebbles are super tiny which is important for her to digest and helps my other kitty who usually eats too fast and throws up. She hardly does that anymore. Unfortunately it's the most expensive of any prescription diet we've ever tried and it is difficult to want to pay it but I'll pay every penny over and over if it keeps my baby healthy and happy. She has energy again and is playing again and that makes my heart happy.
This is the only food my cat can eat - it has been on back order for months - When will it be available again??
My cat was recently switched to the z/d formula. She looked at me like I was stupid when I put this in front of her and walked away. She would not eat it. I tried over several days. Starving was the better option to her rather than eating this food. It was like rubber and stuck to the fork and I felt the food was nasty but presented it to her anyway. I Had to switch back to other food and call my vet for other options as my cat refused to eat any of the food. There is only one flavor and the cans need to be smaller and the food more appealing to cats.
We have two Abyssinian cats that each had severe gastrointestinal issues. Also, one was subject to frequent urinary infections. 10 years now on ZD and only small amounts of cooked chicken and they are doing well. Before our Vet prescribed ZD we had been referred to specialists and thousands of dollars in tests with no good results. Both cats love the dry ZD. Will stay with this!
My cat, Callie, liked the dry food mixed with her usual dry food. Callie's itching was greatly reduced, her ear was getting better and she hadn't vomited since beginning Z/d. When she was converted to Science diet Z/d completely she stopped eating it. She would not eat the Z/d wet food. I had to switch to a competitor and she began vomiting again. I am also concerned about GMO's. It seems to me that a 4 lb. bag of dry cat food should be guaranteed NON-GMO and Organic!
I have a cat with allergies and she would scratch herself raw. She eats the canned z/d and she also eats the dry d/d formula. She is a very picky eater and a grazer so one day she may gulp it all down and the next she picks at it all day but her coat looks great and she no longer scratches herself down to her skin. I agree with a lot of the others who have posted that the texture is a little weird, but I use a fork and flake it up and if you do that first, you can't tell it from the other kind of canned food. Give that a try and see if that doesn't help your cat accept it. Also I will warm it in the microwave for just a few seconds,,not to get it hot hot but just to get the chill off and the aroma intensifies. Hope this helps all!!
I just recently started feed this to my 12 y/o cat for stomach issues she recently developed. I have to agree with the review stating the canned food is not worth buying as it doesn't look like regular canned food and my cat won't touch it and she's not picky. She will eat the dry. I also agree that the price is insane! This is not the first prescription food I have bought as my other cat is on k/d and there are many more choices for the canned and cost is still high but reasonable.
This is a good product but my cat refused to eat it due to the consistency of the wet food. She loves the dry food.
