What causes cat allergies in humans
You may be capable to tell that you own a cat allergy based on the timing of your symptoms. If you start to cough, sneeze, feel itchy, or develop a rash correct after visiting your friend who has a cat, then you might own an allergy to the cat.
Sometimes it can be hard to know that a cat allergy is causing your symptoms, especially if you live with the cat. While some people are allergic to every cats, you might be allergic to a cat even if you own not had allergies to other cats in the past—this can make the effects hard to figure out.
You may also own a hidden exposure to cat allergens, such as when moving to a new home where a cat used to live.
If you own a rash or persistent upper respiratory symptoms, you should see your doctor. After a history and physical examination, your doctor may do some diagnostic tests.
Blood tests can include an IgE level to see if you own an allergic reaction.
Skin Prick Test
You may be advised to own a skin prick test.
This would involve your doctor placing a little quantity of the cat hair or skin on your skin with a needle. You would then be observed for about half an hour to see if you develop a reaction.
Sick as a Dog
For dogs, the most common clinical signs are skin inflammation and itching, Farnsworth says. Other symptoms may include sneezing and runny noses. (Take National Geographic’s dog quiz.)
Cats’ allergy symptoms can manifest as miliary dermatitis, which shows up as little scabs or missing hair, typically around the head and neck area, though it can happen elsewhere, she says.
It’s always significant to observe how endless symptoms happen in your pet—for instance, year-round symptoms may indicate a food allergy or reaction to something else in their environment that’s not seasonal.
Luckily, pets can be tested for a variety of environmental allergens—both seasonal and non-seasonal, saysChristine Cain,of the University of Pennsylvania School of Veterinary Medicine.
"We routinely test dogs for reactions to cat dander," she says.
"This includes a little quantity of allergen placed under the skin to test for reactions, just love in human allergy testing," Cain says.
Generally, veterinarians will glance for common allergens "like dust mites and human dander, or things we encounter in the environment love feathers, sheep wool, or pollens," says Washington State University’s Farnsworth.
Those are the usual suspects, but as with us, Farnsworth says, pets can be allergic to anything, and it can be hard to figure out the culprit with general testing.
You can experience symptoms of a cat allergy correct when you enter into a room or home where a cat lives. Or the effects can start after you spend several hours in the area or with the cat.
A cat allergy can produce upper respiratory symptoms or may affect your skin.
Common effects f a cat allergy can include:
- A runny or stuffy nose
- Red, itchy, or watery eyes
- A skin rash, redness, or itching
- Sore throat
While it is rare, swelling of the face, throat, or any part of the body can develop due to a cat allergy. If you develop swelling or become short of breath, seek medical attention immediately.
Cat allergies are more common than dog allergies, but this does not own anything to do with how friendly the cat or the person is.
Cat allergies are not associated with how much you love a cat or how much the cat likes you.
Getting along with your cat or a friend's cat is a completely diverse issue than having an allergy.
It’s Not Me, It’s You
So what if your pet is allergic to you?
"It always makes owners helpful of unhappy if their reaction is to human dander," Cain says, but happily the two of you don’t own to part. (See "Why Do We Get Allergies?")
"If we own a patient that reacts to human dander, generally they react to other allergens as well," she says.
That means your vet can treat the pet’s allergy, either with allergy shots or oral drops that contain little amounts of the problem allergens.
This retrains your pet’s system to ignore the allergen.
Of course, the cat might always be faking an allergy in hopes you’ll get rid of the dog.

Allergies to cats are fairly common, affecting up to 25 percent of people who also own other types of allergies.
A cat allergy can cause symptoms such as red eyes and sneezing. These allergies can be triggered by direct exposure to cats or by indirect exposure through fabric or air.
You may notice a cat allergy based on the timing of your symptoms. Sometimes, getting medical anti-allergy treatment can assist. But avoiding the cat may be necessary.
You don't need to own shut contact with a cat to develop allergic symptoms.
Some people can own the effects of a cat allergy after coming into contact with fabric, such as a blanket or clothing, that was touched by a cat. And you may even develop symptoms from breathing air in an area where a cat lives.
Cat allergies are triggered by cat hair, skin, saliva, sweat, urine, blood, and dander. Cat dander is a tiny material shed by cats. The dander is airborne and sticky. The size of the cat dander particles is extremely small and it is inhaled deep into the lungs.
Dander can be present in public places, even where there are no cats—because it can be carried on the clothing of people who own cats and then shed in public places.
Allergens are harmless substances that trigger an allergic reaction.
Several proteins that are produced by cats, including Fel d 1, Fel d 4, and albumin own been identified as cat allergens. These allergens trigger a rapid immune reaction mediated by an antibody called IgE. The IgE antibody rapidly activates an inflammatory response that produces the symptoms of a cat allergy.
Cat allergens are produced in large amounts and are extremely potent. Cat allergens are partially under hormonal control.
They are particularly prominent in male non-neutered cats.
Cats generally are not bathed, and they use their own saliva to groom and clean themselves. This can spread the allergen if it is present in the cat's saliva.
Infections Caused by Cats
A parasitic infection caused byToxoplasma gondii (T.
gondii) is spread by cat feces. This parasite is extremely dangerous for pregnant women because it can cause birth defects.
Infections caused by cats are diverse than allergies.
An Overview of Toxoplasmosis
For people with a cat allergy, avoidance of cats is the mainstay of therapy. However, cat owners may not desire to part with their pets, despite the symptoms they endure.
Allergy medications may control symptoms, but in numerous instances, symptoms may persist if the person lives with one or more indoor cats.
Allergy shots may also be a treatment option for people who are allergic to their own pet cats.
There are some ways to decrease cat allergen exposure for cat owners:
- Wipe the cat with a wet cloth or hand towel daily
- Have cats stay exterior, in the garage, or in a part of the home with an uncarpeted floor
- Keep the cat away from the bedroom and the bedroom door
- Vacuum frequently with a high-efficiency particulate air (HEPA) equipped vacuum cleaner
- Bath the cat at least once or twice a week
- Use a HEPA room air cleaner for use in the bedroom and/or other parts of the home (it is best to hold the HEPA filter off of the floor to avoid stirring up more dust)
- Keep the cats away from air vents to the bedroom
- Ensure the cat is neutered
- Follow home dust mite avoidance precautions
If the above measures do not assist to reduce allergic symptoms, you may need to remove your pet cats from your home.
This is especially significant if you or someone in your home has uncontrolled asthma.
Cat dander will persist for months in the home even if the cat is gone – therefore it is significant to clean thoroughly.
- Launder or dry clean every bedding and curtains
- Vacuum every hard floors
- Steam clean every carpets and upholstered furniture
- Wipe below every hard surfaces and furniture
- Replace any air conditioner and heater vent filters
A Expression From Verywell
You may be disappointed to discover that you own a cat allergy.
Parting with a beloved cat can be unhappy.
There own been some suggestions that hypoallergenic cats may be available, but this concept has not been proven. Some experts own suggested vaccinating cats tor feeding them a certain diet to reduce allergic reactions in owners. These are new strategies that are not widely used.
Keep in mind that even if you are allergic to one cat, you might not be allergic to every of them. And numerous other pets might not trigger an allergy for you—such as dogs, bunnies, birds, and fish.
You can develop a psychological aversion to being around a cat if you tend to own allergic symptoms after your cat encounters.
Cat dander is a common cause of allergic asthma, and cat owners who are allergic to cats are more prone to the development of asthma symptoms.
While it is not common, you could own an allergy to cat food or to material in the cat's littler box, rather than an allergy to the cat.
Hold this in mind when you are observing your reactions and when you get tested.
Oversensitive immune system
If you own allergic rhinitis, your natural defence against infection and illness (your immune system) will react to an allergen as if it were harmful.
If your immune system is oversensitive, it’ll react to allergens by producing antibodies to fight them off.
Antibodies are special proteins in the blood that are generally produced to fight viruses and infections.
Allergic reactions do not happen the first time you come into contact with an allergen.
The immune system has to recognise and «memorise» it before producing antibodies to fight it. This process is known as sensitisation.
After you develop sensitivity to an allergen, it’ll be detected by antibodies called immunoglobulin E (IgE) whenever it comes into contact with the inside of your nose and throat.
These antibodies cause cells to release a number of chemicals, including histamine, which can cause the inside layer of your nose (the mucous membrane) to become inflamed and produce too much mucus.
This is what causes the typical symptoms of sneezing and a blocked or runny nose.
