What are Cat Allergies?
Imagine your cat happily exploring the house, only to start itching and sneezing out of the blue. That’s what allergies do. When a cat’s body becomes sensitive to substances in their environment, these substances, known as allergens, can trigger an immune response. Whether it’s something they breathe in, eat, or come into contact with, these allergens can make life pretty uncomfortable for them. Allergies can sometimes overlap with food intolerance, making it a bit tricky to pinpoint the exact cause. Here are the four most common types of allergies in cats:
Types of Allergies in Cats
- Environmental Allergies: These include pollen, grass, mold, dust, fungi, perfume, cigarette smoke, and cleaning products, which can all cause severe allergic reactions.
- Food Allergies: Certain foods can cause skin itchiness, vomiting, and diarrhea. Identifying the culprit food and switching the diet can help.
- Flea Allergies: Flea bites can also cause allergic reactions. The saliva from a tiny flea bite can affect the entire body.
- Atopic Dermatitis: This skin condition occurs when a cat’s body reacts to allergies, causing sores, scabbing, hair loss, and redness.
Food Allergies in Cats
Food allergies are the third most common type of allergy in cats, right behind flea bites and inhaled substances. Extreme itchiness is often the first sign of a food allergy, manifesting as small, pale, fluid-filled lumps on the skin. Dr. Carolyn McDaniel, a lecturer in clinical sciences at Cornell University’s College of Veterinary Medicine, points out that these itchy erupts usually target the head and neck area. But the symptoms don’t stop at the skin. About 10-15% of cats with food allergies also experience gastrointestinal issues like vomiting and diarrhea.
Most Common Food Allergies in Cats
You might be surprised to learn that some of the most common ingredients in cat food can be allergens. These include animal proteins such as:
- Beef
- Fish
- Chicken
- Dairy Products
Other potential allergens are wheat, corn, lamb, egg, barley, rabbit, and even gluten. It’s a bit of a puzzle, right? But don’t worry, we’ve got some solutions!
Common Food Allergies in Cats Symptoms
Identifying food allergies in cats isn’t always very simple. Allergy symptoms can initially be subtle but may become more severe over time. Look for:
- Itching and scratching
- Sneezing and wheezing
- Gastrointestinal problems such as Vomiting and diarrhea
- Overgrooming
- Biting
- Skin inflammation
- Skin or ear infections
It takes time for these symptoms to develop, so patience is key in figuring out the cause.
Best Hypoallergenic Cat Food Options
Food allergies are one of the most common allergies in cats, and finding the right diet can help manage these issues. Given below are some top options to support your cat’s overall wellness:
Novel Protein Diets
A novel protein is simply a new protein your cat hasn’t tried before. If common proteins like chicken and fish are causing issues, try less common meats such as venison, sardines, or salmon. These new protein sources can help avoid allergic reactions.
Pros | Cons |
Can result in healthier skin and coats due to reduced allergens. | These diets may not be readily available at all pet stores. |
Introduces new protein sources like duck, venison, or rabbit, adding dietary variety. | Some cats might be picky and may not readily accept new protein sources. |
Limited Ingredient Diets
Limited-ingredient diets (or elimination diets) are great because they have fewer components, making it easier to pinpoint and avoid allergens. Many LID foods are also free from eggs, soy, grains, preservatives, and artificial additives. Grain-free diets also fall under this category. Some cats are sensitive to grains like wheat, corn, and soy, which can cause allergic reactions and digestive issues. Grain-free cat food eliminates these allergens and focuses on alternative nutrition sources, prompting better health and digestion.
Pros | Cons |
Often free from eggs, soy, grains, preservatives, and artificial additives | Not all LID foods are nutritionally balanced. |
Gentle on the digestive system for pets with sensitive stomachs. | Pets might need time to adjust to the new diet. |
Hydrolyzed Protein Diets
In cats with food allergies, the immune system mistakenly identifies some proteins as harmful, triggering an allergic reaction. Hydrolyzed protein diets (both wet or dry cat food) address this by breaking down protein molecules into smaller, more digestible fragments, which are less likely to be recognized by the cat’s immune system.
Pros | Cons |
Can be beneficial for pets with gastrointestinal issues. | Often more expensive than standard pet foods. |
Can enhance the absorption of nutrients in the digestive tract | Not suitable for all pets; some may not respond to or need this specialized diet. |
Raw Food Diet
A raw food diet can be beneficial for cats with allergies as it avoids potential allergens found in regular cat food. By eliminating fillers like grains or certain vegetables, a raw diet can help prevent allergic reactions.
Pros | Cons |
Provide essential fatty acids and high-quality proteins that may enhance skin and coat health | Poses a risk of bacterial contamination, which can affect both cats and humans. |
Mimics a cat’s natural diet, which may be more biologically appropriate for your cat’s digestive health. | Requires time and effort, including handling and storing raw meat properly. |
Homemade Allergy-Friendly Cat Food
By preparing meals at home, you can control the ingredients and avoid common allergens that may be present in commercial cat foods (dry or wet cat food). One of the many benefits of homemade cat food is the ability to customize recipes based on your cat’s unique dietary requirements. Additionally, homemade foods can promote better digestion and overall health. Fresh ingredients often contain more nutrients than processed food, which can lead to improved energy levels and a healthier coat.
Pros | Cons |
Can tailor the ingredients to avoid allergens specific to your cat. | Requires more time compared to commercial options. |
Avoids hidden preservatives, fillers, and additives found in some commercial foods. | High-quality ingredients can be expensive, potentially making it costlier. |
Transitioning to a New Diet
Switching up your cat’s food might seem like a straightforward task, just pick up the new bag of kibble and pour it in, right? Well, it’s actually a bit more complicated than that. If you’re thinking of switching to a new diet, it’s important to make the change gradually. Our experts suggest a smooth transition over a 7 to 10-day period to keep things easy on your cat’s tummy. A gradual transition helps avoid stomach upsets and allows your furball to get used to the new taste and texture without any fuss. Below is a suggested timeline:
- Days 1-3: Mix 75% of the current food with 25% of the new food.
- Days 4-6: Mix 50% of the current food with 50% of the new food.
- Days 7-9: Mix 25% of the current food with 75% of the new food.
- Day 10 onwards: Transition to 100% of the new food.
And here’s a little tip: consider introducing a rotational diet. By rotating between different foods, you’re preventing your cat from getting too accustomed to just one flavor or brand. Whether you change it daily, weekly, or monthly, the idea is to keep things exciting and prevent any stress from a sudden change in diet. This approach can benefit cats of all life stages. If your cat refuses the new food, try warming it slightly or mixing in a small amount of a favorite treat. And always consult a veterinarian if you have any concerns.
