Complete Overview of Hill's Prescription Diet Z/D Skin/Food Sensitivities Dry Cat Food

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.

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.

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?

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.

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.
