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.
Let’s start by asking – would you realize if your cat needed to cut down?
You know your cat is purr-fect. It’s fluffy and has a paunchy belly. But so, what? It could also imply that it is perfectly healthy. Naturally, you may not understand if your fluffball is on the portly side. In fact, overweight cats now appear to outnumber those who have a healthy weight.
Overfeeding your cat is a big no-no. Even a few additional pounds can increase your cat’s risk of developing certain health conditions, such as type 2 diabetes. It may even prevent your cat from grooming itself properly. Therefore, keeping your cat in shape is crucial to maintain its health, and help it live longer and happier. Well, the good news is that by making some simple dietary and exercise changes, you can assist your overweight cat in losing weight.
Obesity is becoming more prevalent in cats, just as it is in humans. It can have long-term consequences on a cat's health, quality of life, and body functioning. Therefore, obesity in cats must be addressed immediately, as it is linked to serious health problems. Here are the risks of cat obesity:
When your cat becomes overweight, its immune system gets weakened, leaving it more susceptible to infection. This includes urinary infection as well as 'stones,' which are caused in overweight cats because they’re less active, drink less water, and urinate lesser than healthy cats.
Around 80% to 90% of obese cats require daily insulin shots as they are more likely to develop diabetes. But, when their excess weight is eliminated, diabetes can often be reversed.
When your cat’s body senses that it is undernourished, for instance, if a regular food supply is interrupted, the fat is moved from reserves into the liver to be used as energy. But a cat’s body is unable to efficiently control this process, resulting in poor liver function and liver failure.
Cats with excess weight have a harder time grooming themselves, which can contribute to skin problems.
Here is a chart for you to understand better –

After you get your overweight cat in shape, your goal must be to maintain it for its good health and longevity. Here are some things you should avoid doing to keep your cat from becoming overweight:
You should avoid free -feeding your cat to prevent it from becoming obese. Set up definite feeding times and keep treats to a minimum.

Your cat is at even more risk of becoming overweight if it does not engage in any outdoor activity. To avoid boredom and prevent weight gain, find some interesting toys, set aside playtime, and make it a priority for your indoor cat. Another approach is to go for a walk outside with your cat on a leash.

Assess how much cat food your cat truly needs with the advice of your vet, based on your cat's activity level and desired weight. Once you've calculated how much food your cat requires, measure the food for each meal. Remember that cats are little, and while the portion may appear small to you, some extra kibbles can make the difference between maintaining weight and gaining weight.

Another way to help your cat lose weight is to increase her activity. Provide cat 'trees' for climbing or teach your cat to play fetch. Buy or create your own toys that encourage exercise. Many cats enjoy chasing lights from pointers or flashlights. One ingenious owner throws her cat's dry food ration a piece at a time! Many cats enjoy learning to walk on a leash. You also can use your cat's natural hunting instinct to help her lose weight. Hide several small portions of her daily food ration around the house. If you have a multi-level home, make your cat use the stairs. Use your imagination but be cautious. Don't let a fat cat get exhausted, overheated, or out of breath. Also, keep in mind that an old cat may not be able to exercise vigorously.
Use playtime, grooming, stroking, or conversation as rewards instead of food treats. If you cannot resist the fat cat who begs for food at the dinner table, remove the cat during dinnertime. If you have a multi-cat household, the consistent winner of the food competition sweepstakes is often obese. If this is the case, separate the cats at mealtimes if possible.
Obesity is easier to prevent than to cure, but it is never too late to reverse it—though it requires long-term patience and commitment. Helping cats lose weight is a slow process. If the amount they eat is severely restricted, the cat risks other health problems.
Increased activity, behavior modification (for both you and your cat), and calorie restriction are your weapons against feline obesity. However, with all these things, it is important to expect a few setbacks and plateaus. It will take at least four months for an obese cat to lose 15% of her starting weight. At that point, have another look at your cat's body condition and go on from there.
Always check with your veterinarian first.
Eliminate all food treats.
Divide the daily food portion into several smaller meals.
Feed a diet formulated specifically for weight loss.
Weigh your cat every two weeks.
Cats should not lose more than 1% to 1.5% of initial weight per week.
Be patient and consistent!
