One of the most common causes of itchiness in cats is allergies. In fact, cats are almost as prone to allergies as people are. Irritants in the air, chemicals, and foods can cause reactions that affect their skin, eyes, airways, and gastrointestinal system. While some allergic reactions are just irritating for a short period of time, others can end up being fatal.
In this post, we’re discussing allergies in cats, how to determine whether your cat has them, and how you can treat them. Here’s what we’ll cover:
Allergies are among the most prevalent health issues in cats. An allergy develops when the feline's immune system overreacts or becomes hypersensitive to foreign substances known as allergens.
Yes, cats can develop allergies just like people do. This occurs as a result of their immune systems becoming vulnerable to environmental toxins. These irritating substances might not bother you or the other animals in your home, but when your pet's body works to get rid of the bothersome substances, they may exhibit a variety of symptoms.
In most cases, a cat with allergy symptoms will have itchy and irritated skin, but between 10% and 15% of affected felines may also experience gastrointestinal symptoms like diarrhea and vomiting. Other common symptoms of allergies in cats include respiratory issues such as coughing, sneezing, and wheezing. There may occasionally be a discharge from the nose or eyes.
There are many things a cat can be allergic to, and most are found in our homes:
If you suspect your cat might be allergic, a comprehensive check by your veterinarian or a veterinary dermatologist is advised because cats frequently have several allergies at the same time.
Feline allergies are typically broken down into three primary categories:
Contrary to popular belief, cat food allergies are not nearly as common as most pet owners think they are. In reality, only 10% of allergic pets have a food allergy, making food the third most common type of allergy in cats.
Felines suffering from food allergies frequently experience:
Cats can develop a food allergy at any time, regardless of their age or diet. It's possible for a cat to become allergic to a food or ingredient they had been eating consistently with no adverse reaction.
Some cats experience severe itching even after only being bitten once or twice because they are allergic to fleas. Felines with flea allergies may lick, bite, or scratch, especially in the areas around the thighs, neck, belly, flanks, and base of the tail.
Using a flea prevention product year-round is the best way to prevent and manage flea allergies. Your vet can recommend a suitable product based on your pet’s individual needs.
Cats can be allergic to environmental allergies such as pollen, mold, dust, dusted litter, covered litter boxes, as well as perfume, cigarette smoke, and cleaning products. These are all products of the environment your pet lives in and could pose health risks to the animal. When possible, try to avoid any products that irritate your cat or aggravate their allergies.
Unlike seasonal allergies in humans, which mainly cause respiratory problems, seasonal allergies in felines usually manifest as atopic dermatitis. A cat is unlikely to get a runny nose, itchy eyes, or watery sinuses. They will instead show skin or throat symptoms and may potentially be sneezing.
Atopic dermatitis or atopy is a skin condition that cats frequently get as a result of allergies.
Your pet may experience skin sores, hair loss, redness, and scabbing as a result of this illness. Depending on the length of the cat's allergy season, atopy can be treated with corticosteroids, antihistamines, and immunosuppressive drug therapy, as well as improving the health of the hair and skin coat using shampoos, sprays, and/or spot-ons.
When a cat comes into contact with an allergic substance, contact allergies cause a localized reaction on the skin. Reactions to shampoos, flea collars, or particular kinds of bedding, such as wool, are a few examples. If the feline is allergic to these compounds, there will be skin rashes and itching where the substances come into contact. The issue is resolved by getting rid of the contact irritant.
Determining what a cat is allergic to can be challenging. If the trigger isn't clear, elimination diets and exclusion trials with various food dishes, cleaning products, medications, and beds may be required in order to figure out what produces an allergic reaction. There are also certain blood and skin tests available to identify specific allergens.
There is no way for cats to avoid allergens altogether, but you can take certain steps to reduce your pet’s exposure to them:
If your cat exhibits allergy symptoms, be sure to visit your vet.
There are a number of different medications available to treat allergies in cats. Some of the most common ones include steroidal medications, antihistamines, and prescription flea control, as well as lotions, ointments, eye drops, and ear drops.
Always consult your veterinarian before giving a new medication to your pet to ensure the appropriate dose and drug is administered.
Allergies cannot be entirely cured, but they can be dealt with. Following are a few different allergy-specific treatment plans.
Some home remedies for feline allergies referenced on the internet include:
Disclaimer: Many of these home remedies are pet care myths with no scientific backing. If you think your cat is allergic to something, be sure to talk to your veterinarian.
Asthma is a disease of the lower airways which affects up to 5% of cats. Although there is some disagreement over what causes cat asthma, the majority of experts agree that it is brought on by an allergic reaction to something the animal inhales.
Allergies are more common in cats with asthma. If your cat suffers from both asthma and allergies, your vet will probably recommend medications that temporarily widen your cat's airways. Corticosteroids and other drugs like them may be used in long-term therapies.
Dealing with allergies in cats can be quite difficult, especially if the allergen is impossible to get rid of such as dust or pollen. Some cats can be kept more comfortable with medicine and may only experience symptoms during certain times of the year.
Some pet insurance plans cover allergy shots and medication that are prescribed by a vet. However, if allergies are considered pre-existing, allergy medications will most likely be excluded from coverage, so be sure to sign up your feline while they are still young and healthy.
