When a cat's body gets sensitive to its environment, it develops allergies. So, if you notice that your cat is feeling unwell and is constantly sneezing or scratching itself, it could be due to cat allergy reactions. These allergens are unpleasant substances that may or may not irritate you, but when your cat's body tries to rid itself of them, it may exhibit a variety of symptoms.
While it’s normal for cats to show different symptoms depending on the allergy, those that affect their breathing are the most serious ones. So, if your cat suffers from breathing issues due to allergies, it can take a life-threatening turn. Sometimes, the itchiness can also cause skin irritation leading your cat to chew on its paws or tail relentlessly.
Fortunately, cat allergy is treatable once the allergen affecting your cat is identified. Therefore, knowing how to detect if your cat has allergies and what’s causing these allergies can help you prevent problems in the future.
The first step toward treating your cat’s allergies is finding out what’s causing them. A visit to the veterinarian is the simplest way to identify your cat’s allergy stimulus.
Causes of cat allergies could be due to several reasons, all of which fall under one of the three categories. These categories are, namely – flea allergy, food allergy, and environmental allergy (atopic dermatitis).
One of the most common cat allergy signs is flea allergies. These allergies are generally caused by flea bites or flea treatment medicine. Excessive itching is the most predominant symptom of this type of allergy. It's likely that your cat is allergic to fleas if you find it scratching or frequently chewing on its fur, especially directly above the tail.
Food allergies in cats can cause vomiting, diarrhea, and even itchy skin, especially around the neck and head. This type of allergic response might cause your cat to shed patches of fur in severe circumstances. In such extreme cases, your vet can help you detect which foods are causing irritation and develop an appropriate diet for your cat.
Environmental allergies may have different triggers, including plants, pollen, and mold. This type of allergy can also be induced by cleaning products, or the fragrance included in some types of cat litter. Another type of environmental allergy is feline atopy. It is commonly known as feline atopic dermatitis, a severe allergic reaction in cats that causes extreme itchiness in their skin. As a result of this condition, your cat may suffer from skin soreness, redness, scabbing, and even hair loss.
Depending on the kind of allergy your cat has, symptoms can range from unpleasant to life-threatening.
Diarrhea is frequently related to staining of the fur around the hind end in some breeds. In normal cats, you can observe some variation in the consistency of their stool. Dietary changes can also cause temporary changes in their stool. But, if you notice frequent semi-liquid or liquid stools for more than two days, you should consult your vet.
There are different causes to why a cat makes a wheezing sound. It could be due to a hairball stuck in its stomach or allergens like pollens, mold, or cigarette smoke. However, this wheezing sound can also be linked to discomfit or stress. Because each cat's triggers are unique, it's critical to be aware of the surroundings and activities in your cat's environment that could be causing stress-related wheezing.

Watery or glossy-looking eyes are other prominent cat allergy signs. While a cat's moist eyes maybe caused by allergens such as mildew dust or household cleaning products, it could also indicate something more serious, such as a bacterial illness or virus.

Itchiness or skin redness in cats is associated with a skin condition called cat dermatitis. When this happens, your cat’s skin becomes swollen, red, and irritated, often with small blisters, as a result of an external agent directly irritating the skin or causing an allergic reaction to it.

If your cat is suffering from moderate allergy symptoms with only limited itching, medicated shampoos or rinses can help.
Anti-itch and anti-inflammatory medicines such as corticosteroids are particularly effective in treating extreme itchiness in cats. When used correctly, they can be quite safe and effective in cats. Consult your vet to identify the best course of action.
Treating your cat with flea preventatives will prevent your cat from being bitten by fleas. Plus, to lessen the chances of your cat being bitten, you should treat your home during the warmer months when fleas are more frequent. In fact, even cats who aren't allergic to fleas should use a flea preventative to avoid tapeworm and other flea-related illnesses.
To figure out which food is causing your cat's allergies, you must first put it on an elimination diet. After that, gradually reintroduce food items until you find the problematic allergen. The top three allergenic protein sources are beef (18%), fish (17%), and chicken (5%). Avoiding these foods will enable your cat's allergic reaction to be less severe.
The most common allergy symptoms in cats are skin reactions, regardless of the cause, and they can appear at any age. Just because your cat didn’t have allergies as a kitten doesn’t mean she won’t have them as an adult. If your cat suffers from any of the following symptoms, take her to the vet for a consultation:
Allergies can vary from cat to cat, so it is important that you work with your vet to make sure your cat gets the best possible treatment. You’ll both be happier as a result.


Cats are sensitive to a wide range of allergies. Cats, like people, can be allergic to a variety of foods, drugs, plants, and other things. However, flea, environmental, and/or food allergies are the most common allergies in cats.
Keeping your home clean, using dust-free and unscented cat litter, using flea preventatives regularly, avoiding excessive fragrances, and not smoking in the house can help keep your cat from being allergic.
If your cat suffers from allergies, some of the most frequent allergic reactions will trigger certain behaviors, conditions, and even symptoms like:
It depends on whether your cat has skin or food allergies. If your cat eats nothing but novel food and water for eight to ten weeks, the allergic symptoms in its skin will fade away. But if it is related to food allergies, then you need to find a diet that works for your cat and stick to it.
Most cats with inhalant allergies are allergic to a variety of allergens. Itching may only persist just several weeks at a time during one or two seasons of the year if the number of allergens is low and seasonal. The cat may scratch frequently if there are a lot of allergens or if they are there all year round.
Cats belong to the Felidae family which also includes tigers and lions. Although your little bundle of cuteness is not as fierce as its other distinct family, it still has similar physiological and nutritional needs. Compared to other pets, cats and kittens need more protein for adequate growth and development. Hence, their guardians need to ensure they include kitten food with high protein in their kitty’s diet.
Kittens need more protein as they need more energy. Hence, when choosing kitten food, you must go for foods with higher protein content. Most kitten food use plant and meat-based protein to meet the kitten’s daily protein requirement. While protein is essential, you must also consider your cat’s allergies and medical diagnosis before choosing any protein for kittens.
High-protein kitten food should contain the appropriate balance of all essential amino acids and good-quality digestible protein alongside other important nutrients. Cats are primarily carnivores, which means they largely depend on meat as their main source of nutrition.
Amino acids are molecules that come together to form protein. Cats need two essential amino acids for their overall growth and well-being, unlike other species that need nine specific amino acids. Hence, when looking for protein for kittens, you should search for the following essential amino acids:
Ideally, all types of kitten food contain protein. However, as cat parents, you should check its percentage daily value to ensure that you get high-protein kitten food for your growing feline friend. Yet, you must know that your kitten’s protein requirement will change as it ages.
Cats need approximately 3.9 grams per kg of their body weight. Hence, cat parents should look for kitten food with high protein for their fur baby. Typically, cats need approximately 35 to 45% protein for better growth and development. Refer to the table below to know the approximate amount of protein content in kitten food:
Cat’s growth stage | Approximate % of protein required |
Kitten | 40-50% |
Adult | 35-40% |
Pregnant/nursing | 45-50% |
Senior | 35-38% |
Protein is an essential element required for your cat’s consistent growth and health. Cats highly depend on protein for energy. Therefore, kitten food high in protein is supposed to be an integral part of your tiny fur baby’s diet not only in their initial years but also as they grow up. When creating a dietary plan for your cat, you must check for the kitten food protein content to ensure you make the right choice. The following are some of the most common sources of protein that will help you make better choices when selecting a cat food brand.
You should look for these meats when buying kitten food with high protein. IAMS Proactive Health Mother and Kitten™ is made with chicken meat and salmon as well as tuna flour, so your kitty can receive the right amount of protein. It supports eye and brain development while also ensuring healthy digestion.
Essentially, all cats need protein for their ideal growth and overall development. But how to identify how much protein is enough for your kitty? Ideally, all adult cats require approximately 35% protein in their diet. According to AAFCO (Association of American Feed Control Officials), cats need a minimum of 30% protein for growth and reproduction and 26% protein for adult maintenance. Poor-quality protein or low protein might lead to indigestion and loss of muscle mass in kittens and cats. Hence, all cat caregivers must ensure to include the optimum quality of protein in their pets’ daily meals.
AAFCO provides nutrient recommendations based on dry matter. This means, if you are feeding wet cat food to your kitten, then you might have to manually calculate its protein content. The following is the formula for calculating wet cat food’s protein content:
Step 1: Find dry matter of the food by subtracting the maximum moisture percentage from 100.
Step 2: Divide the minimum crude protein by the per cent of dry matter.
Step 3: Multiply its result by 100 to get the result of the percentage of protein available in the dry matter of the meal.
