1. What Are Food Allergies and How Do They Affect Cats?

Food allergies in cats are an abnormal immune response to certain dietary components, such as proteins, cereals, and dairy.

When a cat consumes an allergen, their immune system mistakenly identifies it as a threat and produces antibodies to fight it. This causes inflammation and irritation in the skin, sinuses, stomach, and intestines.

Some signs and symptoms of feline food allergies include:

  • Scratching and itching
  • Hair loss and bald patches
  • Redness and inflammation of the skin
  • Ear infections and head shaking
  • Vomiting and diarrhea
  • Decreased appetite and weight loss
  • Lethargy and depression

Food allergies can affect cats of any age, breed, or gender. The most common allergens for cats are beef, poultry, fish, eggs, corn, wheat, and soy, although any ingredient can trigger an allergic reaction.

2. How to Identify Food Allergies in Your Cat?

If you suspect that your cat has a dietary allergy, it is important to consult with your veterinarian immediately. They will examine your cat and rule out other potential causes such as parasites, infections, and environmental factors.

The most accurate method for diagnosing dietary allergies in cats is through an elimination diet. This involves providing your cat with a novel or hydrolyzed protein diet for eight to twelve weeks and observing their symptoms.

A novel protein is one to which your cat has never been exposed, such as rabbit, duck, venison, or kangaroo. Hydrolyzed proteins are broken down into tiny molecules that are less likely to be recognized by your cat’s immune system, such as hydrolyzed soy or chicken.

If your cat’s symptoms improve or subside during the trial, it is likely that they were allergic to a component of their previous diet.

To determine which ingredient is causing the issue, you can reintroduce each ingredient individually and observe your cat’s reaction. If the symptoms recur or worsen when the allergen is reintroduced, your cat is allergic to that ingredient.

3. What Are Hypoallergenic Cat Foods and How Do They Work?

Hypoallergenic cat food is formulated to exclude or minimize common allergens and ingredients that can trigger an immune response in some cats, such as beef, fish, chicken, wheat, corn, soy, dairy, and eggs.

When a cat is allergic to a particular ingredient, their immune system mistakes it for a threat and produces antibodies to fight it. This causes inflammation and irritation in the body, leading to food allergy symptoms.

The primary protein sources in hypoallergenic cat food are either novel proteins or hydrolyzed proteins. Novel proteins are uncommon sources of animal protein that a cat has not been exposed to before, such as rabbit, venison, duck, turkey, and lamb.

Hydrolyzed proteins are proteins that have been broken down into very small particles that are less likely to be recognized by the immune system, such as soy, rice, and others.

By using novel or hydrolyzed proteins, hypoallergenic cat food reduces the likelihood of your cat experiencing an allergic reaction. They also provide a balanced and complete diet that meets your cat’s nutritional requirements and promotes overall health.

Choosing the best hypoallergenic cat food for your pet can be challenging, with many options and factors to consider. Here are some guidelines and suggestions to help you choose:

5.1 Consult with your veterinarian before transitioning to hypoallergenic cat food

They can diagnose your cat’s dietary allergies or sensitivities and recommend an appropriate hypoallergenic diet. Your veterinarian can also monitor your cat’s progress and adjust their diet as needed.

5.2 Carefully review the ingredient list and avoid any ingredients to which your cat is allergic, sensitive, or known to cause allergies in cats

Look for hypoallergenic cat food with high-quality protein as the first ingredient and minimal fillers, additives, preservatives, artificial colors, and flavors. Avoid unfamiliar or suspicious-sounding ingredients.

5.3 Choose a hypoallergenic cat diet that contains novel or hydrolyzed proteins as the primary source of protein

These proteins are less likely to cause an allergic reaction in your cat and can provide the amino acids they require. Examples of novel proteins include rabbit, venison, duck, turkey, and lamb, among others. Soy and rice are examples of hydrolyzed proteins.

5.4 Consider your cat’s preferences and palatability when selecting a hypoallergenic cat food

Choose a moist or dry formula based on whether your cat prefers wet or dry food. Some cats may prefer one over the other or have preferences for particular textures or flavors. Find a hypoallergenic cat food that your cat enjoys and that satisfies their appetite.

5.5 Introduce the new hypoallergenic cat food gradually and monitor your cat’s reaction over several weeks

Start by mixing a small amount of the new food with your cat’s old food, and increase the amount of the new food over time. This can help your cat adjust to the new diet and prevent digestive problems.

Observe your cat’s behavior, appetite, feces, weight, and fur, and note any improvements or changes. Consult with your veterinarian and try a different hypoallergenic cat food if you observe adverse effects or no improvement.
