Does Bathing A Cat Help With Dander?

Introduction

Cat dander is made up of tiny, microscopic pieces of cat skin that cats naturally shed. These dander particles float in the air, and when inhaled by people who are allergic, can trigger allergic reactions like coughing, sneezing, runny nose, and itchy eyes. Some people with severe cat allergies can even experience asthma attacks from breathing in the dander. With cats being such popular pets, finding ways to manage cat allergies is important for many households.

This article aims to examine whether bathing a cat regularly can help reduce the amount of dander they shed, potentially minimizing allergy symptoms for people sensitive to cat dander. We’ll look at the effectiveness of cat baths, alternative approaches, and considerations around living comfortably with cats when you have allergies.

What is Cat Dander?

Cat dander is made up of tiny, microscopic flakes of skin shed by cats (Source 1). These skin cells contain Fel d 1, a protein found in cat saliva, skin and urine that acts as an allergen (Source 2). Cat dander particles are extremely light and tiny, ranging from 2 to 10 micrometers in size, allowing them to become airborne very easily (Source 3).

Once in the air, cat dander can remain suspended for long periods of time. The jagged shape of the particles makes cat dander adept at sticking to surfaces like furniture, carpets, clothing and bedding. All of these factors allow cat dander to widely circulate through environments, triggering allergic reactions in sensitive individuals.

Who is Affected by Cat Dander?

Cat dander allergies are relatively common, especially among people who have asthma or other allergies. According to the Asthma and Allergy Foundation of America, around twice as many people are allergic to cats compared to dogs.

People who are allergic to cats can experience symptoms like sneezing, coughing, runny nose, itchy eyes, and other upper respiratory symptoms when exposed to cat dander. For some, symptoms may become severe. Asthma attacks can be triggered by cat allergens. A European study published in Pediatric Allergy and Immunology found that over 65% of school children with asthma had allergic reactions to cats.

The main allergen in cat dander that causes issues for people is a protein called Fel d 1. People with cat allergies and asthma have elevated levels of antibodies for Fel d 1. Even very small amounts of cat dander in the air can provoke allergy and asthma symptoms in sensitive individuals. https://onlinelibrary.wiley.com/doi/pdf/10.1111/pai.12602

Do Baths Reduce Cat Dander?

While bathing a cat can temporarily wash away some of the dander on their fur, it does not provide a lasting reduction in dander or allergens (source). Dander builds up quickly in a cat’s fur, so any reduction from a bath is typically short-lived. The water itself does not remove the allergens from the skin and fur. Special hypoallergenic shampoos can help wash away some dander, but not entirely (source).

Frequently bathing cats can also cause problems. Washing too often can strip oils from their skin and coat, leading to dry, flaky skin that sheds more dander. Excessive bathing can irritate sensitive skin and cause overgrooming as the cat tries to replace lost oils. This creates more dander production (source). While an occasional bath may provide temporary relief, it is not an effective long-term solution for reducing allergens.

More Effective Ways to Reduce Dander

While bathing cats does not significantly reduce dander, there are several more effective ways to minimize dander in your home:

Regularly brushing or combing your cat can help remove loose hairs and dander before they are shed around your home. Use a stainless steel comb or slicker brush designed for cats. Brush at least once a week, up to once a day during heavy shedding seasons. Be gentle and brush in the direction of hair growth [1].

Using a HEPA air purifier can capture dander floating in the air. Place air purifiers in rooms where your cat spends the most time, and run them continuously [2].

Vacuum carpets, furniture, curtains, and other surfaces at least twice a week to remove accumulated dander and hair. Use a vacuum with a HEPA filter. Pay special attention to places your cat frequents like cat trees, beds, and window perches [3].

Wash your cat’s beds, blankets, and other washable items regularly to remove dander. Use hot water and add baking soda or allergen-reducing detergent.

Keep your cat out of bedrooms as much as possible, and use HEPA air purifiers in sleeping areas. Close doors to limit dander spread.

Should You Bathe Your Cat?

Occasional baths are not harmful to most cats but offer limited dander reduction, based on research. The National Cat Groomers Institute of America recommends bathing a cat every 4-6 weeks (https://vetericyn.com/blog/how-often-should-you-bathe-a-cat/). However, the focus for reducing dander is often better placed on other methods like regular grooming, vacuuming, washing bedding, and using cat-safe anti-dander sprays. Excessive bathing, such as every 2 weeks, can damage a cat’s skin and fur coat (https://www.purina.co.uk/articles/cats/health/daily-care/do-cats-need-baths).

Most experts advise bathing cats only when necessary, not on a fixed schedule. Signs that your cat may need a bath include strong odors, excessive shedding, visible dirt/grime accumulation, or skin/coat issues. Otherwise, cats are very effective self-groomers and may not need human assistance bathing. Excessive bathing can strip beneficial oils from a cat’s coat and skin, leading to dryness, irritation, and skin infections. It can also cause stress and anxiety for some cats.

Before deciding to bathe your cat, consult your veterinarian on appropriate bathing frequency for your cat’s specific circumstances. Focus on regular brushing, vacuuming, washing bedding, and grooming as safer long-term approaches. Use bathing only as an occasional supplement when your cat clearly needs it.

Seeking Veterinary Advice

For those with severe cat allergies that significantly impact their quality of life, consulting a veterinarian is recommended. The vet can provide advice on minimizing dander and managing allergy symptoms when living with cats. They may prescribe allergy medications, recommend specific diets or nutritional supplements to reduce dander production in cats, or discuss other ways to reduce exposure.

There are some medications veterinarians may prescribe to cats that can help reduce dander levels. Cyclosporine is an immunosuppressive medication that can reduce skin inflammation and dander in cats with allergies. Omega-3 fatty acid supplements may also help minimze dander by reducing skin inflammation. Your vet can determine if these medications may be appropriate for your cat.

When meeting with your vet, be prepared to discuss your allergy symptoms and their severity, steps you’ve already taken to manage the allergies, and your preferences for minimizing dander while keeping your cat happy and healthy. Keep an open dialogue with your vet and work together to find the best solutions for you and your pet’s needs.

Considering Non-Dander Cats

Some cat breeds are known to produce less dander than others, such as the Sphynx cat breed. The Sphynx, with its lack of fur, has very little hair and dander to shed (https://perfectpets.com.au/best-pet-blog/post/hypoallergenic-cats). However, no cat is truly hypoallergenic. While breeds like the Sphynx may help some allergy sufferers, they can still trigger allergies in sensitive individuals.

Adopting a mixed breed or rescue cat may be an option for finding a lower dander cat. Since mixed breeds have diverse genetics, some may naturally produce less dander. Rescue groups may be able to help match you with a cat that seems less likely to aggravate allergies. However, there are no guarantees with rescue cats. It’s important to spend time with any potential cat ahead of adoption to see if they trigger allergy symptoms.

While non-dander or hypoallergenic cat breeds can reduce allergens for some people, they are not a foolproof solution. Consult an allergist to determine your sensitivity level before adopting any cat. Be prepared to manage allergies through other methods if you decide to welcome a feline friend into your home.

Living Comfortably with Cats

If you or someone you live with is allergic to cats but you still want to keep your furry friends around, there are some steps you can take to reduce allergy symptoms and live more comfortably together.

One of the most effective things you can do is keep cats out of bedrooms and restrict them from certain areas of your home. Keeping them out of carpeted rooms and off furniture can reduce the amount of dander that accumulates in places where you spend a lot of time. Shutting them out of bedrooms at night can provide an allergen-free place for you to sleep undisturbed.

Air purifiers with HEPA filters are great for capturing dander particles and clearing allergens from the air. Run them continuously in rooms where your cat spends time. Frequently vacuuming upholstery and carpet, preferably with a vacuum that has a HEPA filter, can also help remove dander from surfaces before it becomes airborne [1].

Over-the-counter antihistamines like cetirizine or loratadine can provide allergy symptom relief if dander exposure is unavoidable. Talk to your doctor about the best options for your situation.

Conclusion

In summary, bathing your cat provides only limited and short-term reduction of cat dander. The dander and allergens will quickly build back up within a couple days of bathing. Instead, the most effective methods for reducing cat dander include frequently grooming and vacuuming, using HEPA air filters, washing bedding regularly, and restricting your cat from certain areas. With proper management, most people with cat allergies can still live relatively comfortably with cats. Focus on keeping your home clean and making your cat feel comfortable and loved.
