Meet the Ultimate Cat Food for Sensitive Cats!

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.

Does This Contain Soy Protein? What About Other Allergens Like Artificial Colors?

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.

My Cat Has Lost His Appetite, and His Coat Looks Dull. Does This Help With Those Problems?

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.

How Much Should I Give My Cat?

The general guidelines for feeding your cat Hill's Prescription Diet cat food is as follows:

Your Cat's Weight Amount per Day

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.

Frequently Asked Questions
What Is the Difference Between Hill's Science Diet and Prescription Diet?

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.

How Do You Know If Your Cat Is Allergic to Their Food?

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:

  • Skin problems, such as redness, rashes, itchiness, wounds, and bald spots
  • Gastrointestinal problems, such as loss of appetite, diarrhea, vomiting, bloating, and nausea
  • Respiratory issues, such as coughing, wheezing, and sneezing
  • Chronic ear infection
  • Developmental delays in young cats
Is Hills Cat Food Hypoallergenic?

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.

Is Hill's Science Diet Safe for Cats?

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.

What Is the Most Common Food Allergy in Cats?

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.

How Do I Know If My Cat Is Allergic to His Food?

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.

What Are Three Symptoms of a Food Allergy?

The most common symptoms of food allergy in cats are:

  • Skin irritation and inflammation
  • Dull or thinning coat
  • Gastrointestinal distress

You should, however, watch out for other signs, such as recurring ear infections and respiratory problems.

How Do You Treat Allergic Dermatitis in Cats?

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.

What Is the One Meat You Should Never Feed Your Cat?

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.

How Long Does It Take for Food Allergies to Go Away in Cats?

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.

What can I feed my cat with food sensitivities?
Answer

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.

Can cats be sensitive to dry food?
Answer

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.

What are the most common cat food sensitivities?
Answer

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.

How do you treat food intolerance in cats?
Answer

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.
