Revealing 7 Effective Ways to Safely Keep Cats for Individuals Allergic to Cat Hair

1. Understanding the Cause of Cat Hair Allergies

Research suggests that genetics play a significant role in the development of allergies. This means that if members of your family have cat hair allergies, you are more likely to develop them as well. Interestingly, cat hair allergies are twice as common as dog allergies. While most people assume they are allergic to cat hair, it is actually a specific protein called Fel-d1 that triggers the allergic symptoms. Those who are allergic to cat hair are actually allergic to this protein, which can be found in:

• Saliva: Cats tend to groom themselves, leaving their saliva on their fur.
• Urine
• Cat dander

Take a look at why cat hair allergies occur.

When the Fel-d1 protein enters the body of someone with an overactive immune system, their body mistakes it for an attack by bacteria or viruses. To protect itself, the body releases histamines, causing symptoms to flare up.

It is important to note that even if you are not personally allergic to cats, they can indirectly trigger allergic reactions. Cats can carry pollen, mold, and other allergens on their fur. Other animals such as mice, hamsters, monkeys, and horses can also cause allergies similar to those caused by cats and dogs.

Breathing in pet hair or coming into contact with these allergens can lead to allergic reactions. Allergens from cats and dogs can cling to clothes, circulate in the air, settle on furniture and beds, and linger in the environment as dust particles.

2. Recognizing the Symptoms of Cat Hair Allergies

Allergic reactions to cats can develop within minutes or take several hours to appear. Approximately 20% to 30% of people with asthma experience severe allergic reactions after exposure to cats. Symptoms may include:

• Sneezing and a runny nose
• Itchy, red, or watery eyes
• Nasal congestion, itching, and stuffiness
• Itchy mouth or throat
• Coughing and wheezing
• Increased pressure and facial pain
• Red and itchy skin where the cat has scratched, bitten, or licked
• Swollen under-eye area with a bluish tint

3. Managing Cat Hair Allergies

How can you determine if you have a cat allergy? While the symptoms of cat allergies may seem obvious, cats may not always be the culprits. It is advisable to confirm the presence of a cat allergy by consulting a physician. Medical professionals can perform skin or blood tests to determine if you have an allergy, although these tests are not always accurate.

Cat allergies can often be controlled using standard cat hair allergy medication. Your doctor may recommend:

• Over-the-counter antihistamines, such as cetirizine (Zyrtec), diphenhydramine (Benadryl), fexofenadine (Allegra), and loratadine (Claritin), or prescription antihistamines like azelastine (Astelin) nasal spray.
• Decongestants, such as over-the-counter pseudoephedrine (Sudafed) or allergy medications containing pseudoephedrine like Allegra-D, Claritin-D, or Zyrtec-D.
• Steroid nasal sprays, which can affect allergic symptoms or hay fever in various ways. Budesonide (Rhinocort), fluticasone (Flonase), and triamcinolone (Nasacort Allergy 24HR) are over-the-counter steroid nasal spray options.

Unfortunately, there is no definitive cure or treatment for cat hair allergies.

4. What to Do If You Have Cat Hair Allergies

a. If You Do Not Have a Cat

For individuals who do not have cats in their homes, they are more likely to be allergic to cat hair rather than urine or dander. While medical treatment can help manage cat allergies, the best approach is to avoid cats and their hair altogether. Here are some tips for managing cat hair allergies:

• Avoid touching, hugging, or kissing cats.
• Exercise caution around cat owners. When visiting their homes, they may inadvertently bring cat hair on their clothes and belongings. This indirect exposure can cause severe allergic reactions in some individuals.
• Plan ahead: If you have to stay in a cat-friendly environment, request that the cat be kept out of the room where you will be sleeping for a few weeks before your arrival. Additionally, start taking allergy medication a few weeks beforehand. Once a cat allergy reaction begins, it can be challenging to control. However, taking medication can help prevent it from occurring in the first place.

b. If You Own a Cat

Managing cat hair allergies or preventing allergic reactions does not mean you have to give up your beloved four-legged companion. Here are some steps you can take to minimize the impact of Fel-d1 protein:

• Keep your cat out of your bedroom: Minimize allergen exposure by washing bed linens, pillowcases, and comforters regularly. Ideally, replace them with specially designed allergen-proof covers that prevent allergens from entering your mattress and pillows. Be patient as results may not be immediate. Cat allergens are about 1/6th the size of pollen, and it may take several months to significantly reduce them.
• Use pet hair rollers: Since cat hair can fly around the room, you can use lint rollers to clean clothes, bedding, and other items. Here are some options for pet hair rollers:

• Use air purifiers: Air purifiers are highly effective in reducing cat hair allergy symptoms. They eliminate impurities, including cat hair and dander, from the living environment. Alternatively, you can invest in robot vacuum cleaners to minimize cat hair. Change the filters on air conditioners and heaters regularly. Maintain indoor humidity at around 40%.

• Regularly bathe and groom your cat: Regular bathing, approximately every 4-6 weeks, helps remove accumulated cat hair, excess fur, and saliva. Since cats dislike water, you should train them from a young age. If you missed this opportunity, you can follow our instructions on how to bathe a resistant cat. Grooming your cat also helps prevent excessive shedding, which disperses allergens throughout the house. Generally, you should brush short-haired cats twice a week and long-haired cats four times a week. However, due to cat hair allergies, you should increase the frequency by one. Discover the best brush type and grooming technique suitable for your cat.
• Keep your home clean: Sofas, under beds and cabinets, rugs, doormats, etc., are paradise for cat hair to cling to. To minimize allergens, you should clean these areas regularly. Vacuuming removes more allergens from the air. When vacuuming, use allergen-blocking vacuum bags or high-efficiency particulate air (HEPA) filter vacuum cleaners. Don’t forget to wear a mask and gloves!
• Limit excessive contact, maintain distance: If you are allergic to cats, it is best to limit close contact with them. You can keep them indoors but avoid letting them into private rooms and your bed. Keep the feeding area away from you, elevated, and covered. Remember to wash your hands thoroughly after contact with cats.

• Minimize allergy traps: Remove allergy traps such as upholstered furniture and carpets. Carpets can accumulate cat allergens 100 times more than hard floors. If removing carpets is not an option, regularly clean them using a vacuum cleaner and steam cleaner if necessary.
• Clean the litter box: Clean the cat litter box as soon as possible after each use. Cat allergens can be found in urine and are left behind in the litter box. To help prevent allergic reactions to the litter box, use a low-dust and clumping cat litter, and ask non-allergic family members to take care of cleaning. Refer to our guide on “How to Clean and Deodorize a Cat Litter Box.”

• Medication: Over-the-counter or prescription antihistamines, eye drops, and nasal sprays can help reduce cat allergy symptoms, although they do not eliminate allergies completely.
• Vaccine: Researchers have successfully developed a hypoallergenic vaccine called HypoCat, which activates the immune system of cats themselves to attack and destroy the Fel-d1 protein. In a study published in the Journal of Allergy and Clinical Immunology, this vaccine was found to significantly reduce the amount of Fel-d1 protein.

Among the 54 cats tested at the University Hospital Zurich in Switzerland, all showed an increase in necessary defense cells to destroy the protein.

Both humans and animals can benefit from this treatment. Individuals with cat allergies are less likely to develop chronic diseases such as asthma. Their cats also do not need to be removed from the home or abandoned. However, this allergy treatment vaccine is still in the developmental stage, making it a potential future solution.

5. Additional Considerations

• Cat hair, especially for individuals with asthma, poses a significant risk. It can cause respiratory system disorders. If you experience difficulty breathing, shortness of breath, or persistent coughing, seek medical attention immediately. If you have severe cat allergies, consult with a doctor about long-term immune therapy for treatment options.
• For individuals who are not severely allergic, with patience and adaptation through the above methods, it is possible to manage cat allergies. If, however, your symptoms persist or worsen despite following all of the methods, consider finding a better home for your furry friend. Ensure that they will be cared for and loved, rather than abandoning them.
• Some studies suggest that early exposure to cats and dogs helps prevent pet allergies. It also increases respiratory immunity during childhood compared to those without exposure. Conversely, a child with an inclination toward allergies may worsen when exposed to pets.

6. Conclusion

If you have cat hair allergies, you are actually allergic to the protein Fel-d1 found in cat saliva, urine, and dander. Essentially, it is impossible to completely eliminate cat allergies. The best course of action is to limit exposure to cats, their urine, and their hair.

You can still keep cats even if you are allergic to them by adopting the following measures:

• Regularly clean your living environment.
• Avoid excessive contact with cats and keep a distance.
• Clean the cat litter box.
• Use air purifiers.
• Bathe and groom your cat regularly.

These methods will help you minimize the impact of cat hair allergies. However, if you find that you are unable to control your allergies despite applying all these methods, consider finding your beloved feline a better home.
