What Cats Cause The Worst Allergies?

Do you love cats but suffer from allergies? Are you tired of constantly sneezing, wheezing, and rubbing your itchy eyes whenever you’re around them? You’re not alone. Studies show that up to 30% of people with allergies are allergic to cats. But did you know that some cats are worse than others when it comes to causing allergic reactions?

In this blog post, we’ll dive into the question of what cats cause the worst allergies. We’ll explore different cat breeds and their potential for triggering allergies. Plus, we’ll uncover what factors make certain cats more allergenic than others. We’ll also discuss common symptoms of cat allergies and provide tips on how to manage them.

Whether you already own a cat and want to know if they’re causing your allergy symptoms or are considering adopting one but want to ensure they won’t trigger your allergies, this post is for you. Get ready to learn everything about which cats cause the worst allergies and how to keep your symptoms under control. So, sit back, relax, and let’s get started.

What is Fel d 1?

If so, you have likely encountered the protein Fel d This insidious protein is found in cat saliva, urine, and dander and is responsible for triggering allergic reactions in humans.

Fel d 1 is not just any protein – it’s small and sticky, allowing it to become airborne when cats groom themselves or shed skin cells. Once inhaled, it can cause a range of allergy symptoms such as sneezing, runny nose, itchy eyes, and asthma attacks.

All cats produce Fel d 1, but some breeds are known to produce higher levels than others. Siamese, Balinese, Russian Blue, Bengal, Sphynx, and Devon Rex are some of the breeds that have been identified as producing higher levels of this protein. However, even cats considered “hypoallergenic” can still produce enough Fel d 1 to cause a reaction in some people.

Research has shown that male cats tend to produce more Fel d 1 than females, with unneutered males being the biggest culprits. However, studies suggest that certain breeds may produce lower levels of Fel d 1 and be better tolerated by people with allergies. Breeds such as Siberian, Balinese-Javanese, Devon Rex, Cornish Rex and Sphynx may be worth considering if you have allergies but still want a feline friend.

It’s important to remember that allergies are complex and can be influenced by many factors beyond just the amount of Fel d 1 present. Even if a cat produces lower levels of this protein, it doesn’t necessarily mean that they won’t cause an allergic reaction. Nevertheless, choosing a breed known to produce lower levels of Fel d 1 may be a helpful step in managing your symptoms.

If you have allergies but still want to enjoy the companionship of a cat, there are steps you can take to minimize your exposure to allergens. Keeping your cat out of certain areas of your home, using HEPA air filters, bathing your cat regularly with hypoallergenic shampoo, and cleaning your home frequently are all helpful strategies to reduce allergen exposure.

Cat Breeds That Are More Likely to Cause Allergic Reactions

It can be disheartening when you want to cuddle with a furry friend but your allergies get in the way. Fortunately, there are some cat breeds that are less likely to cause allergic reactions than others.

The allergen that triggers allergic reactions in cat lovers is called Fel d 1, and it’s found in the cat’s saliva, dander, and urine. While all cats produce this allergen to some degree, some breeds produce more of it than others.

If you’re looking to adopt a cat but want to minimize your exposure to allergens, here are some breeds that may be worth considering:

  • Siberian
  • Balinese-Javanese
  • What Cats Cause The Worst Allergies-2

  • Devon Rex
  • Cornish Rex
  • Sphynx

On the flip side, there are also breeds that are more likely to cause allergies due to the high levels of allergens they produce. One such breed is the Siamese which has a shorter coat than most cats, producing less dander but more saliva. This means that they produce more allergens overall.

Another breed known for causing allergies is the hairless Sphynx cat. Without fur to trap allergens, they easily spread them throughout the house despite producing less dander.

Similarly, the Devon Rex has a curly coat that sheds very little but still produces a lot of saliva, which means they produce more allergens.

Other breeds that are known for causing allergies include the Balinese, Bengal, Burmese, Cornish Rex, and Oriental Shorthair. However, it’s important to note that while these breeds are more likely to cause allergic reactions in some people, it does not mean that all cats of these breeds will cause allergies. It’s always important to spend time with a cat before adopting to see if you have an allergic reaction.

Can Hypoallergenic Breeds Still Cause Allergic Reactions?

The answer is not a simple yes or no. While certain breeds are marketed as hypoallergenic, no breed is completely free of allergens that can trigger reactions in humans.

It’s crucial to understand that the protein responsible for causing allergic reactions in humans is found in a cat’s saliva, urine, and dander. All cats produce this protein to some degree. However, certain breeds have been found to produce less of this allergen than others, making them potentially more tolerable for people with allergies. These breeds include the Sphynx, Devon Rex, Balinese, Siberian, and Russian Blue.

It’s important to note that while some individuals may tolerate these breeds better than others, everyone’s immune system reacts differently. Therefore, it’s essential for anyone considering getting a cat to spend time around different breeds before making a final decision. This will help determine which breed may be the most suitable for their specific allergies.

Moreover, individuals with allergies can take proactive steps to minimize allergens in their home. Regular grooming and cleaning can help reduce the amount of allergens in living spaces. This includes frequently bathing the cat, vacuuming carpets and furniture regularly, and using air purifiers with HEPA filters.

How to Minimize Exposure to Allergens

Living with a feline companion can be challenging, but it doesn’t mean you need to give up on your dream of having a furry friend. By taking steps to minimize exposure to allergens, you can enjoy the company of a cat without suffering from allergic reactions. Here are five effective ways to minimize exposure to allergens from cats.

Keep Your Home Clean:

The first step in minimizing exposure to allergens is to keep your home clean. This involves regular vacuuming with a HEPA filter vacuum cleaner, washing bedding and curtains frequently in hot water, and dusting surfaces with a damp cloth. By keeping your home clean, you can reduce the amount of cat dander and hair that accumulates in your living space, making it easier to breathe and reducing your risk of an allergic reaction.

Bathe Your Cat Regularly:

Another important step is to keep your cat clean. Regular grooming helps remove excess hair and dander, and bathing your cat occasionally can also help reduce allergens on their fur. You can use wipes specifically designed for cats to help remove dander from their coats or invest in a cat shampoo that’s safe for their skin.

Create a Designated Space for Your Cat:

Creating a designated space for your cat is an excellent way to control the amount of hair and dander that spreads throughout your home. This could be a separate room or a designated area in your living room, where you can easily clean surfaces and floors regularly.

Invest in High-Quality Air Filters:

Investing in high-quality air filters for your home is crucial when dealing with allergies. HEPA filters are particularly effective at removing allergens from the air, but you can also consider other types of air purifiers that use ionization or UV light technology to remove allergens.

Choose a Hypoallergenic Breed:

Choosing a hypoallergenic breed of cat is a great option if you’re considering getting a cat but have a history of allergies. Breeds such as Sphynx and Devon Rex produce less dander and hair than other cats, making them less likely to cause an allergic reaction. However, it’s important to note that no cat breed is completely hypoallergenic, and some individuals may still have allergic reactions even to these breeds.

Tips for Choosing the Right Cat for Your Home

Choosing the right cat for your home can be a challenging task, especially if you or someone in your household has allergies. However, there are several tips and tricks you can follow to minimize potential allergens and find the perfect feline companion for your family.

Spend Time Around Cats

Before making a decision, it’s crucial to spend time around cats to see if you have an allergic reaction. You can visit a friend who has a cat, spend some time at a local shelter, or even consider fostering a cat temporarily before making a permanent commitment. This will help you determine which specific breeds or individuals trigger your allergies.

Consider Hypoallergenic Breeds

Some breeds produce fewer allergens than others. Hypoallergenic breeds include the Balinese, Devon Rex, Sphynx, and Siberian. However, keep in mind that no cat breed is completely hypoallergenic, and individual cats within a breed may still produce allergens. Consulting with your doctor or allergist can also provide valuable insight and advice.

Pay Attention to Grooming Habits

Grooming habits can play a significant role in reducing potential allergens. Cats that groom themselves frequently may spread more allergens through their saliva and dander. Long-haired cats may also require more grooming and shed more, which can contribute to allergies. Regular brushing and bathing can remove dander and saliva from the cat’s fur.

Opt for Adult Cats

While kittens are adorable, they may trigger allergies more than adult cats. Adult cats’ allergenicity is already established, making it easier to determine if they will be a good fit for your household. Additionally, adult cats are typically less active than kittens and tend to shed less.

Keep Your Home Clean

Proper care and maintenance can help reduce allergens in the home. Vacuuming regularly, using air purifiers, and washing bedding can help keep allergens at bay. Regular grooming and bathing of your cat can also make a significant difference in minimizing potential allergens.

The Benefits of Bathing Your Cat Regularly

Let’s explore the many advantages of bathing your cat regularly and why it’s essential to make it a part of your pet care routine.

Reducing Dander

Dander is a common allergen for many people and is made up of tiny flakes of skin that are shed by cats. Regular bathing can help to reduce the amount of dander in your home, which can minimize allergic reactions. By keeping your cat’s fur clean and well-groomed, you can create a happier and healthier environment for everyone in your household.

Removing Dirt and Debris

Another benefit of regular bathing is that it can help to remove any dirt or debris from your cat’s fur. This is particularly crucial if your feline friend spends time outdoors or has long hair that is prone to matting. By keeping their fur clean and free from tangles, you can prevent skin irritation and other health issues.

Preventing Parasites

Fleas are a common problem for many cats, and they can cause a range of health issues such as skin irritation, hair loss, and anemia in severe cases. Regular bathing can help to reduce the risk of fleas and other parasites by keeping your cat’s fur clean and healthy. Additionally, using flea prevention products as recommended by your veterinarian can further protect your furry friend from these pesky pests.

Bonding with Your Cat

Bathing your cat regularly can be a great way to strengthen the bond between you and your pet. Many cats enjoy being groomed and pampered, making regular bathing a fun way to spend quality time together. Just be sure to use gentle products that are specifically formulated for feline use, as harsh chemicals can irritate your cat’s skin.

Other Benefits

In addition to the benefits mentioned above, bathing your cat regularly can also help to:

  • Keep their fur shiny and healthy
  • Reduce shedding
  • Prevent hairballs
  • Detect and address any skin issues early on

Cleaning Your Home and Using HEPA Air Filters

Fear not, as there are several steps you can take to create a healthier environment for you and your pets. Regular cleaning is crucial in managing allergies, including vacuuming carpets and furniture, dusting surfaces, and washing bedding frequently. But sometimes cleaning alone may not be enough.

HEPA air filters can be a lifesaver when it comes to capturing tiny particles like pet dander and dust mites that trigger allergies. These filters work by using advanced technology to trap allergens in the air effectively. When purchasing a HEPA filter, make sure to look for one with a MERV rating of at least 11 or 12, indicating how well the filter can trap particles of different sizes.

It’s essential to replace HEPA filters regularly to ensure their effectiveness in reducing allergens. The manufacturer’s instructions will give you guidance on how often to replace the filter. Additionally, it’s also a good idea to limit the areas where your cat is allowed in your home. Keeping them out of bedrooms and other areas where you spend a lot of time can help reduce your exposure to allergens.


In conclusion, cat allergies can be a frustrating and challenging issue for many feline lovers. However, it’s important to remember that not all cats are created equal when it comes to triggering allergic reactions. Some breeds produce more of the allergen protein Fel d 1 than others, which can lead to increased sensitivity in some individuals.

Fortunately, there are several breeds known for producing lower levels of Fel d 1, including Siberian, Balinese-Javanese, Devon Rex, Cornish Rex, and Sphynx. While no breed is completely hypoallergenic and individual cats within a breed may still produce allergens, these options may be better tolerated by those with allergies.

To minimize exposure to allergens from cats, regular grooming and cleaning are essential. This helps reduce the amount of dander and hair in living spaces that can trigger allergy symptoms. Additionally, HEPA air filters are highly effective at capturing tiny particles like pet dander and dust mites.

When choosing the right cat for your home, careful consideration of various factors such as grooming habits, age, and breed is key. Spending time around different cats before making a final decision can help determine which breed may be the most suitable for your specific allergies.
