1. What Exactly Are Food Allergies in Cats?
Food allergies in cats, scientifically known as cutaneous adverse food reactions (CAFR), are a prevalent issue where the cat’s immune system mistakenly identifies a food ingredient, typically a protein or complex carbohydrate, as a threat. This immune response triggers the production of antibodies, leading to inflammation and discomfort for your feline companion. It’s worth noting that allergies can develop even to foods your cat has consumed for extended periods, as the body needs time to build up these antibodies.
1.1. Understanding the Immune Response
The immune system’s overreaction is at the heart of food allergies. When a cat consumes an allergen, the immune system releases substances like histamine, which cause itching, inflammation, and other allergic symptoms.
1.2. Genetic Predisposition and Environmental Factors
While the precise cause of food allergies remains elusive, a combination of genetic predisposition and environmental factors is believed to play a significant role. Some cats may inherit a higher likelihood of developing allergies, while exposure to certain foods early in life can also influence the development of allergies.
2. What Are The Most Common Food Allergies In Cats And Their Symptoms?
Although cats can develop allergies to virtually any protein or carbohydrate they’ve been exposed to, some culprits are more common than others. The usual suspects include beef, fish, chicken, and dairy products. Less frequently, cats may react to wheat, corn, lamb, egg, barley, and even rabbit. Recognizing the signs of these allergies is essential for ensuring your cat’s well-being.
2.1. Beef Allergy
Beef is a common ingredient in many commercial cat foods. A beef allergy can manifest through skin issues such as itching and dermatitis.
2.2. Fish Allergy
Despite being a popular flavor, fish is a known allergen for some cats. Symptoms can include gastrointestinal upset and skin problems.
2.3. Chicken Allergy
Chicken is widely used in cat food, making it a common allergen. Allergic reactions may present as chronic itching and skin lesions.
2.4. Dairy Allergy
Dairy products can be problematic for cats due to lactose intolerance and potential allergic reactions. Symptoms can include digestive issues like vomiting and diarrhea.
2.5. Other Less Common Allergens
While less common, ingredients like wheat, corn, lamb, egg, and rabbit can also trigger allergic reactions in sensitive cats. Vigilance in monitoring your cat’s response to these foods is crucial.
2.6. The Prominent Signs of Feline Food Allergies
The most common sign of food allergies in cats is chronic itching, often accompanied by skin lesions and hair loss. This itching typically affects areas such as the face, ears, belly, groin, armpits, legs, and paws.
2.7. Gradual Intensification of Allergic Reactions
Because it takes time for a cat’s immune system to build antibodies against certain proteins or carbohydrates, the signs of an allergic reaction will also take time to manifest and likely intensify over time.
2.8. Additional Symptoms to Watch For
In addition to chronic itching and skin inflammation, some cats may also develop recurrent skin and ear infections. Gastrointestinal signs, such as vomiting, diarrhea, and scooting, may also be present. In some cases, cats may develop inflammatory bowel disease.
3. Diagnosing Food Allergies in Cats: What’s The Process?
The most reliable method for diagnosing food allergy (CAFR) in cats is an elimination diet trial. This involves feeding a diet that does not contain any proteins your cat has been previously exposed to. The trial can take at least eight weeks and should be supervised by a veterinarian. During the trial, it is crucial to eliminate all other treats, supplements, and edible products to ensure accurate results.
3.1. The Elimination Diet Trial: A Detailed Look
An elimination diet trial is a meticulous process that requires dedication and patience. The goal is to remove all potential allergens from your cat’s diet and then reintroduce them one by one to identify the specific allergen causing the reaction.
3.2. Novel Protein Diets vs. Hydrolyzed Protein Diets
Test diets are either a “novel” protein diet (no previous exposure to that protein) or hydrolyzed protein (protein that has been modified so that it is not allergenic). Manufacturing, handling, and packaging of the diet is also important.
3.3. Why Over-The-Counter Diets May Not Suffice
There are not many over-the-counter diets that meet the criteria for an appropriate food trial. There are dry and canned prescription diets available for food allergy patients. Home cooking may also be needed in some cases.
3.4. Debunking Inaccurate Allergy Tests
While there are blood, saliva, and hair “tests” commercially available to “diagnose” food allergy in pets, they are not recommended as they are not accurate or reliable. Relying on these tests can lead to misdiagnosis and ineffective treatment plans.
4. What Happens During a Food Trial For Cats? A Step-By-Step Guide
Your veterinarian or veterinary dermatologist will guide you on how to successfully administer a food trial for your cat. Only feed your cat the prescribed diet and water and ensure that monthly preventatives, like heartworm and ectoparasite preventatives, are not flavored. The success of a food trial hinges on strict adherence to the veterinarian’s guidelines.
4.1. Essential Tips for Starting a Food Trial
- Thoroughly clean all food bowls with soap and water before beginning the new diet.
- Ensure all family pets are separated at feeding time. Pick up bowls after feeding. Do not permit the pet on the trial to lick or eat from another pet’s bowl. If that occurs, the trial must be restarted. You may want to consider transitioning all household pets to the trial diet. If different diets are fed, provide separate food and water bowls.
- Introduce the trial diet gradually over three to seven days to prevent stomach upset. Do this by mixing equal quantities of your cat’s original diet with the new diet, gradually withdrawing the original diet. Save one to two weeks of the original diet for rechallenge later if needed.
- Suspend use of treats and any other potential allergen sources. Heartworm and ectoparasite (flea) preventatives must be topical or nonflavored.
- Do not give medications to your pet in any food or pill pockets. Ask your veterinary dermatologist before giving any supplements or medications during the food trial.
4.2. The Duration of a Diagnostic Food Trial
Diagnostic food trials are typically eight weeks in duration. The immune system generally takes four weeks to adjust to the new diet and up to eight weeks to see an improvement or reduction of your cat’s clinical signs.
5. Treating Food Allergies in Cats: What Are The Available Options?
Depending on the interpretation of the diagnostic food trial, your veterinarian may prescribe a retrial. The initial challenge is done with the original diet. If CAFR is confirmed, you may elect to return and feed the prescribed diet for your cat’s life. Managing food allergies in cats involves identifying the offending allergen and making long-term dietary adjustments.
5.1. The Importance of Rechallenge
There are times when your veterinary dermatologist may recommend a rechallenge, such as if there is a need to identify the specific offending allergen. During this process, your pet remains on the trial diet while single ingredients are introduced one at a time. Each introduced allergen is fed for 10-14 days to monitor for a flare in signs.
5.2. Identifying Specific Allergens
The reintroductions could include meats (chicken, turkey, beef, pork, white fish, salmon, lamb, etc.), grains and carbohydrates (rice, oat, wheat, etc.), dairy (milk, cheese), and egg. Pinpointing the exact allergen allows for a more targeted and effective dietary management plan.
5.3. Long-Term Dietary Management
Once your cat’s allergen is identified, it’s important to avoid all treats, supplements, and foods that contain the allergen. Retail pet foods labeled as “limited-ingredient” may not be suitable for cats with food allergies due to the risk of cross-contamination.
5.4. Why Regular Veterinary Follow-Ups Are Crucial
Regular follow-ups with your veterinarian are necessary to monitor your cat’s progress and make any necessary adjustments to their diet. These check-ups ensure that your cat remains healthy and comfortable.
6. What Foods Should Cats With Allergies Avoid?
Knowing which foods to avoid is just as important as knowing what to feed. Here’s a breakdown of common allergens and suitable alternatives.
| Allergen | Potential Symptoms | Alternatives |
|---|---|---|
| Beef | Itching, skin lesions, gastrointestinal upset | Novel proteins like duck or venison |
| Fish | Vomiting, diarrhea, skin inflammation | Chicken or turkey |
