Cat Food For Allergies

Cats, for the most part, are healthy. However, sometimes, like us humans, do experience some problems, even allergies. These problems can range from the itchy and dry skin to some serious ear infections. Food allergies are real. However, what most cat parents do not realize is that human allergies are different from cat allergies.

For humans, the symptoms are usually vomiting, diarrhea, nausea and stomach upsets. With cats, the main symptoms pertaining food allergies tend to overlap with symptoms of other conditions and diseases. As such, most times cats are misdiagnosed. A skilled vet is required to give the right diagnosis.

Food Allergies in Cats Explained

Studies show that approximately 10% of all cat allergies are related to food. Out of all the food allergies, 60% of these cause itchiness and scratching. Some of the most common allergies in cats include flea bite allergies, inhalant allergies, and food allergies. Food allergies develop at any point in a cat's life. But generally, most cats will develop allergies between the ages of 2 and six years and the allergy will be to some of the foods that they feed on frequently. Yes, allergies are quite something. They seem to target what your cat loves best.

While there is a lot of evidence pointing to the idea that most cats tend to develop allergies to the foods that they feed on most, the actual process of how the allergies develop is not fully understood. All researchers and professionals in the field know is that cats have a complex antibody response that occurs within the digestive system. Food allergies in female and male cats are equal. The same case applies to unaltered and altered cats. However, some cat breeds seem to experience slightly more food allergies compared to others. But there is no scientific proof to link these breeds to their susceptibility to food allergies.

Another fact that most pet owners do not seem to understand (you need to be a different cat parent) is that there is a difference between food intolerance and food allergies. Food allergies most often than not cause symptoms affecting the skin while food intolerance affects the gastrointestinal tract.

In humans, for instance, food intolerance would present itself as diarrhea or stomach upsets right after eating some spicy foods. On the other hand, a food allergy would trigger a chemical chain reaction in the body leading itchy skin, excessive scratching, and loss of hair in patches. The best way to differentiate itchy skin caused by a food allergy and that caused by other allergies is that food allergies may appear all year round even after an environmental change.

How To Treat Food Allergies in Your Cat

There is no two way about it. For you to diagnose your cat’s food allergies, you will have to pay close attention to him and report any, and all symptoms noticed to a professional. Your vet, after reviewing the symptoms presented may request some test to help in ruling out some other forms of allergies.

If a food allergy is found to be the cause of the symptoms manifesting, then there is only one option - to determine the allergen and removing it from your cat’s diet. Unfortunately, this process is easier said than done. The process is tedious and may take a few weeks before determining the allergen. Some of the most common culprits include wheat, corn, soy, eggs, beef, fish, dairy, and chicken. During this process, you should also bear in mind that there is a possibility for your cat to be allergic to multiple foods.

The diet and food trial mentioned above is recommended by your vet. The treatment plan lasts for several weeks. During the first 12 weeks, the goal is to get rid of all potential allergens from your cat’s body. After the 12 weeks have passed, you now introduce the allergens one at a time being keen on your cat’s response to the food. If a negative reaction is experienced, chances are you have found the culprit causing your cat discomfort. After identifying the allergens, the last step as earlier pointed out is ridding it from your cat’s diet.

How To Feed a Kitty With Allergies

During the process of elimination (trying to get your cat to feel better), you will need to keep it on a diet that is free of the common food allergens mentioned above. Unfortunately, most commercial foods contain these allergens and as such, you will need to switch to different allergens food formulas altogether. You might even have to change the brand during the elimination phase.

So what kinds of foods are you left with you ask? Well, your options may be limited, but at least you have options. Your food options include Limited Ingredient Diet. This diet includes novel sources of carbs and proteins. What is meant by novel source? These are foods that contain protein and carb sources that your cat has not eaten before and are as such unlikely to have developed an allergy. Examples of these food sources include venison, duck, and rabbit for protein and potatoes and peas for carbs.

The fact that your cat is in the elimination phase is no reason not to have a balanced diet.  He still needs to get the right nutrition in his body to maintain a healthy body. The change is difficult, I know, but it is manageable. That said, you should always be ready to compare the different cat commercial foods against each other to determine which is least likely to trigger an allergic reaction. Some of these major brands include Nature’s Variety and Blue Buffalo Limited Ingredient Diets. These are by far the best options to start with. But you are still left with the task of examining the list of ingredients.

In addition to choosing the right foods, you need to transition your cat slowly. Do not make the change sudden as this could lead to problems with your cat’s digestive system.  But ultimately, it is up to you to want to prevent these effects or not. I personally preferred to be on the safe side and took things slow.

If you do choose to take things slow, you will need to start by mixing small amounts of the current food with the new food. Start with a ratio of 25% to 75% of new food to old food. Maintain this ratio for a few days and then bump it up to 50% to 50 %. Retain this ratio for a few days until your cat is on the new food diet entirely.


The above is the best cat food for allergies you can trust to help you treat your beloved feline's allergies. They are designed for this specific goal. All products are natural, and most of the products are gain and wheat free. Be sure to make the transition slow and smooth to avoid getting adverse effects.
