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 are known to be finicky and picky about a lot of things. Their pickiness in terms of toys and activities is fine and completely natural; if it extends to their eating, things could get a little concerning. If your cat is a picky eater, you can try a few remedies such as serving them different food items. If they still turn away from the food served, you should consult a vet. However, before drawing any conclusions, it is necessary to understand that it is in a cat’s nature to be fussy. And while your feline friend may be stubborn initially, they tend to adapt to a set routine eventually. So, here is a brief guide to help you better understand your cat’s pickiness about food.
There are certain reasons why your cat turns from the food served. This behaviour may not necessarily indicate that your cat is a finicky eater.
If your cat is refusing to eat food served to them, it is possible that they are not hungry. Some possible reasons for this could be that they have been munching throughout the day and have had a lot of treats. If your cat does roam around outdoors by themselves, it is entirely possible that they switched to their hunting instincts and caught prey.
If you notice your cat has not eaten in more than 24 hours, it might be a sign of an underlying weakness and it is best to consult a vet in this matter.
Improper routine
Despite being finicky, cats are creatures who thrive on routine. So, when it comes to their daily feeding, it is best to establish a routine and stick to it. If your cat is not served meals at regular times, they may refuse to eat.
If you have not cleaned your cat’s serving plate before pouring in their food, they may not enjoy the meal. Cats may refuse to eat out of a soiled bowl or plate, so ensure that your pet’s serving dish is always clean.
A lot of cats tend to enjoy eating alone. They do not like consuming meals in the presence of others or being the centre of attention during meal times.
If your cat starts eating less, you may want to look for a factor that could be causing stress. Has another animal been added to the household? Has a family member left or died? Have the cat's surroundings changed, such as a move to a new house? When the stress is removed, your cat will probably go back to a normal diet. If your cat seems healthy, happy, and lively, and has a good coat and clear eyes, there is little cause for concern. Cats also have an uncanny ability to smell changes in the world around them. Even a new bowl can disturb a cat's eating habits. Some cats refuse to eat from plastic or hard rubber bowls.
Medical factors also could contribute to a change in your cat’s eating habits. The only way to verify this is to visit a veterinarian. If the medical examination does not verify that a problem exists, your cat may be manipulating you in grand style!
If your cat is a picky eater and it’s tough to get them to finish a meal, here are some tips you could try:
Heat wet food before serving
Cats have a strong sense of smell and enjoy food by its aroma. If the wet food you served them has gone cold, it may not give off the aroma that cats love. So, heating the meal a little may help.
Clean the serving dish/bowl
Since cats have a strong sense of smell, they will know if their serving bowl is unclean. If so, it can quickly kill their appetite and they may turn away from the food. So, ensure that you always serve meals to your cat in a clean dish/bowl.
Add chicken broth/tuna water/cat oil to their food
Try to entice your cat to eat food by adding a little amount of warm chicken broth, tuna water, or cat oil to the meal. This will significantly improve the smell of the food for the cats. However, do be sure to never serve anything containing onions, chives, or garlic, as these ingredients can be harmful to a cat.
Try different foods
If your cat is still refusing to eat, it may be time to change the food. You may have to try a different product and hope your pet likes the new one.
If despite trying everything your cat still won’t eat, it is time to consult your vet. Also, if your cat has gone more than 24 hours without eating anything, you should visit the vet immediately as your pet could be ill.
If your cat is set on a routine that needs to be changed, make the change slowly and gradually. Your cat may not like a sudden switch in things and can continue to refuse to eat. If you wish to switch your fur baby over to different food, start off by mixing a little quantity of the new food with their current food, over the span of a few days. Gradually, increase the quantity of the new food item until it is the only thing being served.
