Understanding Cat Food Allergies and Intolerances

A food allergy in cats occurs when their immune system mistakenly identifies a specific food ingredient, usually a protein, as a harmful invader. This misidentification triggers an immune response, leading to the production of antibodies that attack the perceived threat, resulting in allergic symptoms. It’s important to differentiate this from a food intolerance, which does not involve the immune system and is typically related to difficulty in digesting certain food components. Food intolerances may improve over time if the triggering ingredient is eliminated.

Recognizing the common signs and symptoms of food allergies is crucial for early intervention. These can manifest in various ways, primarily affecting the skin and the digestive system.

• Skin Issues: Itchy skin (pruritus) is a very common sign, often leading to overgrooming, hair loss, and the development of inflamed skin, redness, rashes, and even lesions or secondary skin infections. Pay close attention to areas like the armpits, inner thighs, and stomach, as well as the head, neck, and back.
• Digestive Issues: Food allergies can also cause gastrointestinal upset, including vomiting, diarrhea, and potentially an increase in hairballs.
• Other less common signs might include sneezing and snoring.

It is essential to consult your veterinarian for a proper diagnosis if you suspect your cat has a food allergy. A vet can help rule out other potential causes of these symptoms, such as flea bites and environmental allergies like pollen, mould, grass, and dust mites. In severe cases, your veterinarian may prescribe skin supplements and medication to provide immediate relief. For environmental triggers, strategies like regular vacuuming and avoiding air fresheners might be suggested.

Common Cat Food Allergens

Contrary to popular belief, protein ingredients, rather than grains, are the most common culprits in feline food allergies. While some cat foods marketed for allergies exclude grains, true grain allergies in cats are considered less prevalent than allergies to animal proteins. However, some cats can be allergic to specific grains like barley, buckwheat, brown rice, bulgar, and oats, and certain proteins in grains can cause intestinal issues.

The most frequently identified food allergens in cats include:

• Animal Proteins: Beef, chicken, fish (although sometimes used as a novel protein in hypoallergenic diets), dairy, and eggs. Chicken and fish are specifically noted as common allergens.
• Grains: While less common, wheat, corn, and soy are often mentioned. Some commercially produced foods avoid grains like wheat.
• Less common allergens could involve ingredients like barley and rabbit.

It’s important to note that cats can develop allergies to food they have been eating for a long time. When trying to identify an allergen, it’s crucial to avoid all forms of the suspected ingredient.

Types of Hypoallergenic Cat Food Diets

Hypoallergenic cat food is specifically formulated to minimize the risk of triggering allergic reactions in sensitive cats by using ingredients that are less likely to cause them. Several types of these diets are available:

• Limited Ingredient Diets (LID): These diets are characterized by a restricted number of ingredients, aiming to reduce the chances of the cat encountering an allergen. They typically feature a single protein source and a limited number of carbohydrates. Opting for foods with transparent ingredient lists is advisable. Brands like Instinct Limited Ingredient (rabbit) and Natural Balance (duck and green pea) are examples.
• Novel Protein Diets: These diets utilize protein sources that the cat has likely never consumed before. By introducing a novel protein, the cat’s immune system is less likely to recognize it as a threat and mount an allergic response. Examples of novel protein sources include duck, venison, rabbit, kangaroo, lamb, insect (cricket, mealworm) (like Concept for Life Veterinary Diet Hypoallergenic – Insect), quail, ostrich, wild boar, and even alligator. AATU 85/15 Dry Cat Food featuring duck is another example.
• Hydrolyzed Protein Diets: These diets contain proteins that have been broken down into very small molecules through a process called hydrolysis. This extensive breakdown makes the proteins significantly less likely to be recognized by the cat’s immune system, thereby reducing the potential for an allergic reaction. These diets often require veterinary authorization. Examples of brands offering hydrolyzed diets include Royal Canin Veterinary (Sensitivity Control, Anallergenic, Hydrolyzed Protein), Hill’s Prescription Diet (z/d Food Sensitivities), Purina Pro Plan Veterinary Diets (Hypoallergenic), and Specific Veterinary Diet. Royal Canin Veterinary formula utilizes hydrolyzed soy protein. Purina HA is also mentioned as a hydrolyzed option.
• Grain-Free Diets: These diets exclude common cereal grains such as wheat and corn. While popular among owners of cats with allergies, it’s important to remember that protein allergies are more common than grain allergies. Grain-free diets often use alternative carbohydrate sources like sweet potatoes, peas, and chickpeas. Brands like Teepee Grain Free offer grain-free options.
• Raw Food Diets: Feeding a raw cat food diet is another potential approach for managing food allergies. These diets often consist of fresh, 100% natural, and easily recognizable ingredients and are typically grain-free and dairy-free. Bella & Duke and Viva Raw are mentioned as providers of raw cat food, with Viva Raw offering single-protein options. When considering a raw diet, it’s crucial to ensure nutritional completeness and safety, and consulting a veterinary nutritionist is advisable.

Choosing the Right Hypoallergenic Cat Food

Selecting the most suitable hypoallergenic cat food for your feline companion requires careful consideration of several factors.

• Key Ingredients to Look For:
  • High-quality or novel protein sources. Look for foods listing a single animal protein source like turkey or lamb.
  • Alternative carbohydrates such as sweet potatoes, peas, and chickpeas.
  • Omega-3 and omega-6 fatty acids, often found in fish oil and flaxseed, to support skin and coat health and help reduce inflammation.
  • Limited and transparent ingredient lists that clearly state each component.
  • Some foods may contain hydrolyzed proteins.
  • Natural probiotics might be included to support gut health.
• Ingredients to Avoid:
  • Known allergens for your specific cat. Carefully check the ingredient list and avoid all forms of the identified allergen (e.g., if your cat is allergic to chicken, avoid chicken, chicken offal, chicken bone, and chicken by-products).
  • Artificial additives and fillers, as these can sometimes cause irritation or sensitivities.
  • Generic terms like ‘cereals’ or ‘meat and animal derivatives’ in the ingredient list, as these can vary between production batches, making it difficult to pinpoint allergens.
• Considering Your Cat’s Specific Needs: Take into account your cat’s age (kitten, adult, senior) and any other pre-existing health conditions.
• Understanding “Hypoallergenic” vs. “Hydrolyzed”: It’s important to understand that “hypoallergenic” is a broad term indicating a lower likelihood of causing an allergic reaction, while “hydrolyzed” refers to a specific protein processing method. The term “hypoallergenic” is not legally protected.

Identifying Your Cat’s Specific Allergies

The most reliable way to determine your cat’s specific food allergies is through an elimination diet trial.

• The Elimination Diet Trial: This involves feeding your cat a single protein source that they have likely never eaten before (a novel protein) for a period of 8-12 weeks. During this time, no other treats, supplements (other than water), or flavored medications should be given to avoid skewing the results. If your cat’s symptoms improve on this restricted diet, the next stage involves gradually reintroducing one old food ingredient at a time every week, carefully observing for any return of allergic symptoms. Maintaining a detailed record of any changes in your cat’s condition is crucial throughout this process. It’s also important to prevent cross-contamination by ensuring separate food and water bowls and cleaning surfaces thoroughly. This process requires patience and can be lengthy.
• Working with Your Veterinarian: Always consult your veterinarian before starting an elimination diet. They can help rule out other medical conditions, guide you through the process, and recommend appropriate novel protein sources.
• Allergy Tests (Blood and Skin Tests): Veterinarians can perform blood tests or intradermal skin tests to identify potential allergens. However, it’s worth noting that home allergy tests are not guaranteed to be accurate. Furthermore, even veterinary allergy tests can sometimes yield false positives if the cat is in a reactive state, and food elimination trials are often considered more reliable for diagnosing food allergies.

Transitioning Your Cat to a New Food

When introducing a new hypoallergenic cat food, a gradual transition is essential to prevent digestive upset.

• Gradual Introduction: Mix a small amount of the new food with your cat’s current food, gradually increasing the proportion of the new food over a period of 7-10 days.
• Maintaining Routine: Keep to a regular feeding schedule.
• Ensuring Fresh Water: Always ensure your cat has access to fresh, clean water, which aids digestion.
• Positive Reinforcement: Offer praise and gentle affection during feeding times to help your cat adjust to the new food.

Long-Term Management of Cat Food Allergies

Once your cat’s food allergens have been identified, strict avoidance is the cornerstone of long-term management.

• Strict Avoidance of Known Allergens: Carefully read the ingredient lists of all cat food, treats, and supplements to ensure they are completely free from the identified allergen.
• Challenges for Outdoor Cats: Managing the diet of cats that go outdoors can be challenging, as they may hunt or be fed by neighbors. Informing neighbors about your cat’s allergies can help prevent accidental exposure. Keeping your cat indoors during an elimination diet is often necessary.
• The Role of Probiotics: Some evidence suggests that natural probiotics or probiotic supplements may support gut health and potentially help cats with autoimmune symptoms like itchy skin.

Specialized hypoallergenic diets, particularly prescription formulas, can often be more expensive than conventional cat food.

• If the specific allergen is known, exploring single-protein foods that avoid that allergen might be a more affordable option.
• Look for discounts and consider subscribe and save options offered by retailers like zooplus (saving 5% on repeat orders) and Petsmart (offering a 35% discount on eligible subscribe and save items).
• While homemade diets are sometimes considered, they require careful planning to ensure nutritional completeness and safety, and consulting a veterinary nutritionist is highly recommended. Homemade diets may not always be cheaper than specialized commercial options, especially when factoring in the cost of necessary supplements.

Food Allergies vs. Food Intolerances (Revisited)

To reiterate, food allergies involve the immune system, while food intolerances are digestive issues. Symptoms of a food intolerance may take longer to fully subside (8-12 weeks) after the offending ingredient is removed from the diet. A true food allergy, however, will not clear up, and avoidance of the allergen is the only way to prevent a reaction.

Conclusion: Best cat food for allergies.

Selecting the right hypoallergenic cat food is crucial for effectively managing your cat’s allergies, alleviating their discomfort, and significantly improving their overall well-being. The key steps in this process include recognizing the symptoms of a food allergy, consulting with your veterinarian for a proper diagnosis, identifying the specific allergens through methods like elimination diets, choosing an appropriate hypoallergenic food (such as novel protein, hydrolyzed protein, or limited ingredient diets), and transitioning your cat to the new food gradually. Remember that managing feline food allergies often requires patience and a strong commitment to the dietary plan. Working closely with your veterinarian throughout this journey is highly recommended to ensure the best possible outcome for your allergic cat.

Best Cat Food For Allergies. (FAQ):

Q1: What are the signs that my cat might have a food allergy or intolerance?
Common signs can include skin issues such as itching, redness, and hair loss, as well as gastrointestinal problems like vomiting and diarrhea. Some cats may also exhibit more general symptoms like lethargy or a poor coat condition. It is important to consult with your veterinarian to properly diagnose the issue.

Q2: What are the most common food allergens in cats?
Beef and chicken are among the most common food allergies in cats. Some cats are also allergic to fish, dairy, and eggs. Contrary to popular belief, protein ingredients are more often the culprits than grains.

Q3: What is the best cat food for allergies?
The best foods for cats with food allergies are ones that are free from the specific food or ingredients that your cat is allergic to. You may also want to consider avoiding processed food, as it can contain grains like wheat and corn, which some cats can be allergic to. Hypoallergenic cat foods are designed to avoid triggering allergic reactions.

Q4: How do I figure out what my cat is allergic to?
An elimination test is the best way to determine what food or ingredient your cat is allergic to. This involves stripping your cat’s diet back to a single protein and feeding this for 8-12 weeks. If your cat shows no signs of an allergy, you can slowly introduce another food type into their diet and feed this for a week. You can approach a food trial with a novel protein or a single-source protein diet. It’s crucial that the elimination diet is not contaminated with any supplements, treats, or drinks other than water. Consult your vet before starting a food-elimination diet. Vets can also perform blood tests or skin tests for food allergies, but these may not always be as accurate as an elimination diet.

Q5: Can I test my cat for allergies?
Yes, food allergy tests for cats are available, but a food elimination test often provides the most accurate results. Veterinary allergy testing may not always pinpoint the specific allergen.

Q6: How long does it take for cat allergies to clear up?
A true food allergy will never clear up, and the only way to prevent an allergic reaction is to avoid food or ingredients you know your cat is allergic to. If your cat has a food intolerance, it can take between 8-12 weeks for symptoms to fully subside after removing the food or ingredient from their diet. Improvement on a new hydrolyzed food diet can take time.

Q7: What should I do if my cat refuses the new food?
