Why do I have allergies to cats?

Hey, fellas, how are you?. Are you uncomfortable with the presence of a cat? Do you feel like you’re sneezing a lot? Do you feel about any kind of allergies? Do not feel strange, as there are many people who are allergic to animals especially cats. In this post we will tell you because I have an allergy to cats.

Nearly a third of people with allergies are allergic to cats and dogs. And twice as much people have cat allergies, more than allergies to dogs. Identifying the cause of your allergies can be difficult when an animal lives in your home. This is because households contain other allergens, such as dust mites, that could cause similar symptoms.


It is important to see an allergist to confirm an allergy to a pet. It can be difficult to admit that the cat you love causes health problems. Many people choose to endure symptoms rather than get rid of their pet. If you are determined to live like this, you can take steps to minimize the symptoms of your allergy.

Read on for signs of cat allergies and what you can do to prevent them.


You don’t need to have a cat to be exposed to the allergen. That’s because you can travel in people’s clothes. Allergy to cats may not appear for several days if your sensitivity or allergen levels are low.

Common signs of a cat allergy usually occur shortly after you come into contact with cat dandruff, saliva, or urine. The allergen of the cat to which more than 90% of people with cat allergies react comes from the saliva and skin of cats. It is found in higher levels in male cats.

The allergen can cause swelling and itching in the membranes surrounding the eyes and nose, usually causing eye inflammation and nasal congestion. Some people may develop a rash on the face, neck, or upper chest in response to the allergen.


Genetics seems to play a role in the development of allergies, which means you’re more likely to experience them if you have family members who are also allergic.

Your immune system produces antibodies to fight substances that could damage your body, such as bacteria and viruses. In a person who has allergies, the immune system mistakes an allergen for something harmful and starts producing antibodies to fight it. This is what causes allergy symptoms, such as itching, runny nose, skin rashes and asthma.

For cat allergies, allergens can come from your cat’s dandruff (dead skin), fur, saliva, and even urine. Breathing in pet dandruff or coming into contact with these allergens can cause an allergic reaction.

Pet allergen particles can be worn in clothing, circulated in the air, accommodated in furniture and bedding, and stayined in dust particles.

Fatigue is common in untreated allergies, such as persistent coughing due to postnasal drip. But symptoms such as fever, chills, nausea or vomiting should be considered related to a disease rather than allergies.

If you are allergic to the cat and the cat allergens enter your lungs, allergens can be combined with antibodies and cause symptoms. These may include shortness of breath, coughing and wheezing. Allergy to cats can cause an acute asthma attack and can trigger chronic asthma.

Up to 30% of people with asthma may have a severe attack when coming into contact with a cat. You should talk to your doctor about a treatment plan if your symptoms become bothersome or uncomfortable.


There are two ways to assess any allergies, including to cats: skin tests and blood tests. There are two types of skin allergy tests. A skin test and an intradermal skin test. Both tests give quick results and tend to cost less than blood tests.

Certain medications can interfere with skin tests, so talk to your doctor about the best test for you. Skin tests are usually performed by an allergist due to the possibility of severe reactions during the test.


This test is done in your doctor’s office so they can observe any reaction. With a clean needle, your doctor will prick the surface of your skin (usually on your forearm or back) and deposit a small amount of the allergen. A multi-allergen test is likely at the same time.

The skin will also be punctured with a control solution that has no allergens. Your doctor may count each prick to identify the allergen. In about 15 to 20 minutes, the site of the skin puncture may turn red or swollen.

This reaction confirms an allergy to that substance. A positive allergy to the cat will usually cause a red, itchy lump in the cat allergen. These unpleasant effects usually go away 30 minutes after the test.


This test is also done in your doctor’s office so they can observe any reaction. Possible allergens may be injected under the skin of the forearm or arm. Red, itchy bumps with a positive reaction will appear.

An intradermal test is considered more sensitive to detect an allergy than a skin test, meaning it may be better to show a positive result when an allergy exists. But it can also have more false positives than the skin test. That means it creates a skin reaction when there’s no allergy.

Both skin tests play a role in allergy testing. Your doctor will explain which test method is best for you.


Some people may not be tested for the skin, often due to an existing skin condition or age. Young children often have more difficulty with skin tests. In these cases, your doctor will order a blood test.

Blood will be drawn in the doctor’s office or in a lab, sent for tests. Your blood is then tested for common allergen antibodies, such as cat dandruff. Results take longer, but there is no risk of an allergic reaction during a blood test.


Avoiding allergen is best, but when that’s not possible, the following treatments may help:

Antihistamines, such as diphenhydramine (Benadryl), loratadine (Claritin), or cethirizine (Zyrtec).

Nasal aerosols of corticosteroids such as fluticasone (Flonase) or mometasone (Nasonex).

Over-the-counter decongestant sprays.

Cromolyn sodium, which prevents the release of chemicals from the immune system and can reduce symptoms.

Leukotriene inhibitors, such as montelukast (Singulair).

Vaccines against allergies known as immunotherapy (a series of injections that desensitize you to an allergen).


Avoiding is best, to avoid allergies in the first place. But if you find out you’re allergic to your cat, there are other options besides getting rid of your pet. Consider these strategies to reduce your symptoms.

  • Keep the cat out of your room.
  • Wash your hands after touching the cat.
  • Remove wall-to-wall carpets and upholstered furniture. Wood or tile floors and clean walls help reduce allergens.
  • Select furniture covers or covers that can be washed with hot water and wash them frequently.
  • Cover the heating and air conditioning vents with a dense filter material like a stud.
  • Install an air filter.
  • Change filters on air conditioning units and furnaces frequently.
  • Keep the humidity level in your home at around 40 percent.
  • Vacuum weekly with a HEPA filter vacuum cleaner.
  • Wear a mask while removing dust or cleaning.
  • Recruit a non-allergic person to do regular cleaning at home and clean the sandbox.
