Many pet owners aren’t aware that cats can cause allergies. In fact, cat allergies are twice as common as dog allergies. The good news is that people can manage their cat allergies with medications, allergen avoidance, and immunotherapy. Creating an allergen-free home environment also helps significantly.
What Are Cat Allergies?
Cat allergies are allergic reactions to proteins found in cat dander (skin flakes), saliva, or urine. The most common allergy is to Fel d 1, a protein secreted by cat sebaceous glands and found in skin flakes. When Fel d 1 particles enter the air, people breathe them in and interact with antibodies, triggering an immune response and allergy symptoms.
Between 10-20% of the general population has cat allergies. For sensitized individuals, symptoms occur minutes after exposure to cat allergens. Different people experience allergy symptoms ranging from mild to severe.
Common Symptoms of Cat Allergies
Common allergy symptoms include:
- Sneezing
- Itchy, watery eyes
- Congestion
- Runny nose
- Coughing
- Wheezing
- Difficulty breathing
- Hives, rashes, or eczema flare-ups
In more severe cases, cat allergies can trigger asthma attacks. Swelling inside the mouth or throat also occurs occasionally. Symptoms typically worsen with prolonged exposure. However, even brief interactions with cats can spur an allergic reaction.
What Causes Cat Allergies?
Cat allergies originate from an overreaction of the immune system to specific proteins in cats. Here’s a quick overview of the science behind cat allergies:
Exposure: Cat allergens in dander and saliva enter the air and are inhaled. Allergens can also get transferred to surfaces like clothing and furniture.
Sensitization: The immune system mistakenly identifies cat allergens as harmful. It makes customized IgE antibodies to target them.
Allergic Response: The next time cat allergens enter the body, IgE antibodies trigger the release of chemicals like histamine. This causes allergy symptoms.
Once the immune system gets sensitized to cat allergens, allergic reactions and symptoms are likely to reoccur with every new exposure.
Diagnosing Cat Allergies
To test for cat allergies, allergists use skin prick tests or blood tests. These tests help identify which substances trigger an allergic response. Common diagnostic tests include:
Skin Prick Test: Drops containing cat allergens are placed on the skin, which is lightly pricked. Swelling indicates an allergy.
Blood Test: Blood is analyzed to measure IgE antibody levels against different allergens like cat dander. Higher levels indicate an allergy.
At-Home Exposure Test: Stop interacting with cats for 1-2 weeks, then monitor symptoms after exposure. Recurring symptoms indicate an allergy.
Pinpointing specific allergy triggers is crucial for treatment and management. An allergist can recommend customized solutions based on test results.
Solutions and Treatments
Fortunately, various effective treatment options can provide symptom relief for cat allergies.
Medications
Antihistamines like cetirizine block the symptom-causing effects of histamine. Nasal sprays containing steroids reduce inflammation in the nasal passages. Inhalers help prevent asthma flare-ups.
Depending on symptom severity, an allergist may prescribe a combination of different oral and nasal allergy medications. Most are available over-the-counter or by prescription.
Allergen Avoidance
Since allergy symptoms stem from reactions to cat proteins, avoiding exposure decreases symptoms for many people. Strategies include:
- Keep cats out of the bedroom
- Bathe cats weekly
- Place an air purifier in rooms where the cat spends time
- Use high efficiency filters in heating/AC systems
- Remove fabrics and carpets which can harbor allergens
- Vacuum frequently using a HEPA filter vacuum
Immunotherapy
Allergy shots introduce small doses of cat allergens to help the body build tolerance over several months. Gradual exposure means fewer symptoms upon contact with cats.
While allergy shots don’t cure allergies, they can substantially reduce symptom severity long-term. About 80-90% of people with cat allergies experience significant improvement after consistent immunotherapy.
Tips for Managing Cat Allergies
In addition to medical treatments, making lifestyle adjustments and cat-proofing your home environment goes a long way towards controlling allergy symptoms. Helpful tips include:
Wash hands after petting cats to remove traces of saliva and dander that could trigger a reaction later.
Avoid touching eyes while interacting with cats or cleaning litter boxes. Transferring allergens near the eyes worsens eye-related allergy symptoms.
Shower and change clothes after prolonged exposure to cats. Dander clung to clothing continues to circulate allergens.
Ask others to help with litter box duties or play time to limit personal contact with allergy triggers.
Cuddle cautiously. Keep cuddles brief and avoid nuzzling your face against your cat, which transfers dander and saliva to mucus membranes.
Implementing lifestyle habits that limit allergen contact makes a significant difference when combined with medical treatments.
Creating an Allergen-Free Environment
While you can’t completely eliminate all cat allergens, it is possible to create a relatively allergen-free environment. Helpful steps include:
Keep cats out of bedrooms. Allowing cats in sleeping areas leads to nighttime allergy issues. Plus, pet dander lingers on bedding. Designate separate human and cat zones.
Bathe cats weekly. Bathing removes much of the Fel d 1 allergen from fur and skin before it sheds. Opt for cat-safe shampoos and gently scrub to lift dirt and dander away.
Groom regularly. Brushing cats 2-3 times per week catches loose hairs before they shed onto household surfaces.
Place an air purifier with a HEPA filter in rooms where cats spend the most time. HEPA filters remove 99.97% of particles, including cat dander floating in the air. Run continuously for best results.
Vacuum frequently using a vacuum with a HEPA filter. This eliminates dander, hair, and other allergens from carpets and upholstery. Wear a protective mask while vacuuming.
Use high efficiency filters in heating and cooling systems to filter airborne allergens. Replace filters regularly.
Remove fabrics. Replace drapes, upholstered furniture, carpets, and area rugs with easy-to-clean leather, wood, and tile whenever possible. Fabrics collect dander and are difficult to deep clean.
With diligent cleaning habits and home modifications, cat owners can still keep their furry friends while controlling allergy symptoms!
Should You Re-Home Your Cat?
Severely allergic owners face the difficult question of whether finding their cat a new home provides the only path to symptom relief. There is no one-size-fits-all answer. Factors to weigh include:
- Symptom severity – Mild symptoms can be managed with treatments, while severe, life-disrupting symptoms may warrant rehoming.
- Efficacy of treatments – If allergy medications and home modifications don’t provide adequate relief, rehoming might emerge as the last resort.
- Emotional bond – Strongly bonded owner-pet relationships may motivate extra effort to make the living situation work.
- Age/life circumstances – Younger cats have better rehoming prospects. Owners entering nursing homes may need to rehome pets.
Ideally, severely allergic owners can manage symptoms sufficiently to keep their beloved cats. But in some unfortunate cases, rehoming leads to the best quality of life for both pet and owner. This difficult choice requires honesty about the level of symptoms and impairments to normal activities you’re willing to withstand.
FAQs
Here are answers to some frequently asked questions about cat allergies:
Unfortunately, no truly hypoallergenic cat breeds exist. All cats produce Fel d 1 protein in their saliva and sebaceous glands. However, a 2012 study found Siberian and Russian Blue cats produce lower levels of Fel d 1 compared to other breeds. Still, individual allergy responses vary significantly.
Yes, some people develop new cat allergies in adulthood even after years of coexisting with cats symptom-free. Repeat exposure over time can trigger antibody production and sensitization. Later-onset cat allergies warrant an appointment with an allergist for testing.
While hairless cats shed less fur, they still release dander and produce allergy-causing Fel d 1 protein. A minority of cat allergy sufferers experience slightly milder symptoms around hairless cats. However, they don’t provide adequate allergy protection for most.
Make an appointment with an allergist if over-the-counter allergy medications and home modifications fail to provide sufficient symptom relief. Allergy testing helps identify precise allergen triggers. Allergists can provide immunotherapy and customized medical management plans tailored to your test results.
Yes, antihistamine eye drops like Ketotifen fumarate can help relieve itchy, watery, red eyes caused by cat allergies. They block the symptom-triggering effects of histamine released during an allergic reaction. Using them alongside oral antihistamines provides additional relief.
Veterinary studies show that cleaning products containing accelerated hydrogen peroxide, like Rescue disinfectants, work best for household surfaces. Hydrogen peroxide destroys allergen proteins through an oxidation reaction. Cleansers with benzalkonium chloride also rated highly at removing cat allergens.
Professional air duct cleaning removes dust, debris, pet hair, and dander trapped in ducts which then circulate allergens through AC systems. Combining duct cleaning with upgraded HVAC filters provides in-depth allergen removal for severely affected homeowners.
Waterless shampoos, foams, and cleansing wipes make good alternatives for aging or ill cats who tolerate bathing poorly. Products like hypoallergenic PET HEAD Dry Clean wipes dissolve dirt, odors, dander, and allergens from fur and skin when rubbed on. They provide mild cleansing for senior cat owners with allergies.
