Overview
A pet allergy can contribute to constant allergy symptoms, as exposure can occur at work, school, day care or in other indoor environments, even if a pet is not present.
Pet Allergy Symptoms
- Sneezing
- Runny or stuffy nose
- Facial pain (from nasal congestion)
- Coughing, chest tightness, shortness of breath and wheezing
- Watery, red or itchy eyes
- Skin rash orhives
Pet Allergy Management and Treatment
- Avoid being around dogs and cats; if you have a pet at home, take specific steps to limit exposure.
- Nasal sprays, antihistamines and bronchodilators can help relieve symptoms.
- Considerallergy shots(immunotherapy).
Do you want to know if it’s Fluffy or Fido causing you to wheeze and sneeze?
It’s time for an allergist.
Cat Allergies
If your nose runs and your eyes water or you start sneezing and wheezing after petting or playing with a cat, you likely have a cat allergy. A cat allergy can contribute to constantallergy symptoms, as exposure can occur at work, school, day care or in other indoor environments, even if a cat is not present.
Cats produce multiple allergens (proteins that can cause allergy). These allergens are found on the fur and skin and in saliva. All cats produce allergens; studies have not shown that cats can be hypoallergenic (meaning that they don’t cause allergy). Homes with more than one cat have higher levels of cat allergens. Characteristics such as the length of a cat’s hair, its sex and the amount of time a cat spends indoors are not associated with cat allergen levels.
Dustandpollenin a cat’s coat can also cause allergy symptoms. In those cases, the allergy is to the dust or pollen, not to the cat.
Of all the pollen, and mold, and animal dander, dust mites that we have studied, the cat dander is absolutely the smallest dander. And what that means is that allergen remains airborne for at least 30 minutes after you disturb it in the room. That just allows the allergic patient to have a constant exposure to that allergen.

Cat Allergy Symptoms
Cat allergy symptoms range from mild to severe, depending on an individual’s sensitivity and the level of exposure to allergens. Those variables may also influence how quickly symptoms develop after exposure. Highly sensitive people can develop symptoms, including breathing problems or a rash, within minutes of touching a cat or entering a house with a cat.
Cat allergy symptoms may include:
- Sneezing or a runny or stuffy nose
- Facial pain (from nasal congestion)
- Coughing, chest tightness, shortness of breath and wheezing
- Watery, red or itchy eyes
- Skin rash orhives
Some people may also develop a rash or hives after being scratched by a cat.
Diagnosing Cat Allergies
Do you suspect you’re suffering from cat allergies? Anallergistcan provide you with a diagnosis and treatment.
A skin-prick test is the most common way of diagnosing a cat allergy. For this test, a small amount of an extract of cat allergen is placed on your skin. Your skin is then pricked with a small, sterile probe, allowing the liquid to seep under the skin’s surface. You’ll then be monitored for swelling and redness or other signs of a reaction, signaling an allergy. Results typically become evident within 15 to 20 minutes.
Even if you’re sure your symptoms are caused by a cat, it’s a good idea to be tested, since the symptoms may actually be caused by other environmental exposures.
Cat Allergy Management and Treatment
Avoidance is the best way to manage a cat allergy. If you have a cat and are allergic to cats, consider removing the cat from the home.
If you have a cat but don’t want to find it a new home, or if your family wants a cat even though someone in the household is allergic, here are some strategies that may help keep symptoms at bay:
- Keep the cat out of your bedroom and restrict it to only a few rooms. Be advised that keeping the cat in only one room will not limit the allergens to that room.
- Don’t pet, hug or kiss the cat; if you do, wash your hands with soap and water.
- High-efficiency particulate air (HEPA) cleaners run continuously in a bedroom or living room can reduce allergen levels over time.
- Regular use of a high-efficiency vacuum cleaner or a central vacuum can reduce allergen levels.
- Giving your cat a bath at least once a week can reduce airborne cat allergen.
Treatments for cat allergy vary, depending on the symptoms.
Your allergist can help determine what treatment would be best to treat your cat allergy. Nasal symptoms often are treated with steroid nasal sprays, oral antihistamines or other oral medications. Eye symptoms are often treated with antihistamine eyedrops. Respiratory or asthma symptoms can be treated with inhaled corticosteroids or bronchodilators to either prevent or relieve respiratory symptoms.
Allergy shots(immunotherapy) are an effective treatment of allergies by building tolerance over time through gradually injecting increasing doses of an allergen.

Dog Allergy
If your nose runs or you start sneezing and wheezing after petting or playing with a dog, you may be allergic to dogs.
Dogs produce multiple allergens, or proteins that can cause allergy. These allergens are found in dog hair, dander, saliva and urine. All dogs produce allergens; studies have not shown that dogs can be hypoallergenic (not cause allergy). Dog allergen levels increase if the dog lives indoors and are higher in the rooms where a dog is allowed.
Dustandpollenin a dog’s coat can also cause allergy symptoms. In those cases, the allergy is to dust or pollen, not to the dog.
If you remove a cat from a home, you clean all the walls down, do the laundry, do the draperies, it still takes six months for the level of cat protein to get down to normal.

Dog Allergy Symptoms
Do you suspect you’re suffering from dog allergies? An allergist can provide proper diagnosis and treatment.
Symptoms may include:
- Sneezing or a runny or stuffy nose
- Facial pain (from nasal congestion)
- Coughing, chest tightness, shortness of breath, and wheezing
- Watery, red or itchy eyes
- Skin rash orhives
Some people may also develop a rash or hives after being scratched or licked by a dog.

Is there an allergy-free dog?
While poodles, Portuguese water dogs and a number of other breeds (including several types of terriers) have a reputation for being hypoallergenic, a truly allergy-free breed does not exist. A2011 studycompared dust samples from homes with dog breeds reported to be hypoallergenic and those of homes with other dogs. The levels of dog allergen in homes with “hypoallergenic” dogs did not differ from the levels in homes with other breeds.
