Cat Allergies: Causes, Symptoms, Diagnosis & Treatment

Cat allergies happen when your body reacts to certain proteins in a cat’s body. These proteins are found in things like cat fur, their spit, and even their pee. Even though many people think it’s the fur that causes allergies, it’s these proteins that are the real troublemakers.

Causes of Cat Allergies

Environmental Factors

Exposure to environmental allergens like pollen, dust mites, and mold can exacerbate cat allergies. These allergens can cling to a cat’s fur, exacerbating allergic reactions in sensitive individuals.

Cat Dander

Cat dander consists of tiny, airborne particles of skin shed by cats. These particles contain proteins that can trigger allergic reactions when inhaled or come into contact with the skin.

Saliva and Urine

Proteins present in a cat’s saliva and urine can also act as allergens. When a cat grooms itself, saliva proteins can dry on its fur and become airborne, contributing to allergic symptoms in susceptible individuals.

What are Different Preventive measures for cat allergies?

Here are some Important methods which help you to avoid these cats’ Allergies.

Regular Grooming: Brushing your cat frequently can help remove loose fur and dander, reducing allergen buildup in your home.

Keep the Cat Clean: Regular baths for your cat can also help minimize allergens. Use cat-specific shampoos and consult your vet for advice.

Hypoallergenic Products: Opt for hypoallergenic cat litter, bedding, and grooming products to reduce exposure to allergens.

Clean Home Environment: Vacuum and dust your home regularly, paying extra attention to areas where your cat spends time.

Wash Bedding and Furnishings: Regularly wash your cat’s bedding, blankets, and any soft furnishings they use to remove allergens.

Designated Cat-Free Zones: Create areas in your home where your cat is not allowed, such as bedrooms, to reduce allergen exposure.

Air Purifiers: Invest in HEPA air purifiers to filter out airborne allergens, including cat dander and other particles.

Outdoor Time: Allow your cat access to outdoor spaces to minimize allergen buildup indoors.

Hand and Clothing Hygiene: Wash your hands and change clothes after handling your cat to remove allergens.

Consult an Allergist: Seek advice from an allergist to develop a personalized plan and explore treatment options.

Seal Cracks and Gaps: Seal any cracks or gaps in your home where allergens may accumulate.

Reduce Upholstered Furniture: Minimize upholstered furniture in your home to reduce surfaces where allergens can collect.

Pet-Free Bedrooms: Keep your bedroom pet-free to ensure a space free from allergens while sleeping.

HEPA Vacuuming: Use a vacuum cleaner with a HEPA filter to effectively remove allergens from carpets and upholstery.

Allergy-Proof Bedding: Use allergen-proof covers for mattresses, pillows, and bedding to create a barrier against allergens.

Diagnosis of cat allergies

Here are the steps involved in diagnosing cat allergies:

Medical History:

Your healthcare provider will start by asking you about your symptoms and any potential triggers. They may inquire about your exposure to cats and whether your symptoms worsen in their presence.

Physical Examination:

A physical examination may be conducted to assess any signs of allergic reactions, such as redness or swelling of the eyes, nasal congestion, or skin rash.

Allergy Testing:

Skin Prick Test: This common allergy test involves applying a small amount of cat allergen extract to the skin, usually on the forearm or back, and then pricking the skin with a needle. If you are allergic to cats, you may develop a small raised bump or redness at the test site within 15-20 minutes.

Blood Test (Specific IgE Test):

Blood tests can measure the levels of specific antibodies (IgE) produced by your immune system in response to cat allergens. High levels of IgE antibodies to cat allergens indicate an allergic reaction.

Patch Testing:

In some cases, patch testing may be performed to identify delayed allergic reactions to cat allergens. Small amounts of allergen are applied to patches, which are then placed on the skin for a specified period.

Elimination Diet:

In cases where food allergies may be contributing to symptoms, an elimination diet may be recommended to identify potential allergens.

Symptom Tracking:

Keeping a diary of your symptoms and potential triggers can help your healthcare provider make a more accurate diagnosis.

Once a diagnosis of cat allergies is confirmed, your healthcare provider will work with you to develop a personalized treatment plan tailored to your specific needs and preferences.

What are the Different Treatment Options for Cat Allergies?

Treatment of cat allergies typically involves a combination of allergen avoidance strategies and medications to manage symptoms. Here are some common medications used to treat cat allergies:

Antihistamines:

These medications work by blocking the effects of histamine, a chemical released by your immune system during allergic reactions. Common antihistamines include:

Loratadine (Claritin)
Cetirizine (Zyrtec)
Fexofenadine (Allegra)
Diphenhydramine (Benadryl)

Nasal Corticosteroids:

These nasal sprays help reduce inflammation in the nasal passages, relieving symptoms such as congestion and runny nose. Examples include:

Fluticasone (Flonase)
Triamcinolone (Nasacort)
Mometasone (Nasonex)

Decongestants:

Decongestants can help relieve nasal congestion by shrinking swollen blood vessels in the nasal passages. They are often available in oral or nasal spray forms. Examples include:

Pseudoephedrine (Sudafed)
Phenylephrine (Neo-Synephrine)
Oxymetazoline (Afrin)

Leukotriene Receptor Antagonists:

These medications block the action of leukotrienes, substances that contribute to allergic inflammation. Montelukast (Singulair) is a common leukotriene receptor antagonist used to treat allergies and asthma.

Eye Drops:

For relief of allergic conjunctivitis (eye allergies), antihistamine eye drops such as:

Ketotifen (Zaditor)
Olopatadine (Patanol, Pataday)
Cromolyn sodium (Opticrom)

Allergy Shots (Immunotherapy):

Immunotherapy involves regular injections of gradually increasing doses of cat allergens to desensitize the immune system over time. This can help reduce the severity of allergic reactions to cats.

It’s important to consult with a healthcare provider or allergist before starting any medication for cat allergies. They can recommend the most appropriate treatment based on your symptoms, medical history, and individual needs.

Additionally, allergen avoidance strategies, such as keeping cats out of certain areas of the home and using air purifiers, can complement medication therapy to help manage cat allergies effectively.

Conclusion

Cat allergies can be bothersome, but with the right strategies, you can still enjoy the company of your feline friend. By understanding what causes allergies, recognizing symptoms, and taking steps to prevent and treat them, you can make living with cat allergies more manageable.
