Are you a cat lover who suffers from allergies? If so, you know the struggle of finding the perfect feline companion.

While some breeds are known for being hypoallergenic, others can trigger severe reactions that leave you feeling miserable.

In this article, I dive into the worst cats for allergies and what makes them particularly troublesome for those with sensitivities. From grooming habits to proteins in their saliva and skin, there are many factors that contribute to a cat’s allergenicity.

So, if you’re considering adopting a furry friend, read on to learn which are the worst cats for allergies and make an informed decision for you and your family’s health.

What Causes Allergies to Cats?

What are the worst cats for allergies?

Allergies to cats are caused by a protein called Fel d 1, which is found in a cat’s skin, saliva, and urine. When cats groom themselves, they spread this protein all over their fur, which can then be transferred to humans through contact or inhalation.

Some people are more sensitive to this protein than others, and even a small amount can trigger an allergic reaction. Symptoms can range from mild to severe and may include sneezing, runny nose, itchy eyes, and even difficulty breathing.

It’s important to note that there is no such thing as a truly hypoallergenic cat. While some breeds may produce less of the Fel d 1 protein, all cats produce it to some degree. Additionally, other factors such as dust and pollen can exacerbate allergies in some people.

Why Some Cats are Worse for Allergies

Not all cats are created equal when it comes to causing allergies. Some cats may produce more allergens than others, while some may have fur that traps more allergens. Here are some possible reasons why some cats are worse for allergies:

  • Fur length: Long-haired cats may trap more allergens in their fur than short-haired cats.

  • Saliva: Cats that groom themselves frequently may spread more allergens through their saliva.

  • Breeds: Some cat breeds may produce more allergens than others, such as Siamese, Devon Rex, and Sphynx cats.

If you are allergic to cats, it is important to do your research before adopting a cat. You may want to consider a hypoallergenic cat breed or a cat with short fur. You may also want to consult with an allergist to determine the best course of action for managing your allergies.

9 Cat Breeds to Avoid for Allergy Sufferers

Cat breeds that produce a lot of the Fel d 1 protein are the worst for allergy sufferers. Here are 9 cat breeds that are known to produce higher levels of this protein:

  • Persian cats – These cats have long, thick fur and shed moderately all year long. They also produce a lot of dander.

  • British Longhair cats – This breed shed all year round and are best avoided if you suffer from allergies.

  • Oriental Longhair cats – Another breed that sheds all year, it also spends a lot of time grooming which means the coat is full of allergens and dander.

  • Exotic Shorthair cats – Yet another constant shedding cat so although the hair is short, its still best avoided for sufferers.

  • Scottish Fold cats – Although they don’t shed all the time, they have thick coats which can be a problem for allergy sufferers

  • Siamese cats – produce higher levels of Fel d 1 protein than other breeds.

  • Himalayan cats – also known as “Himmies,” are a cross between Siamese and Persian cats and also produce high levels of Fel d 1 protein.

  • Devon Rex – while Deven Rex cats are good for some allergy sufferers, they can produce more saliva than other breeds, which can increase the amount of Fel d 1 protein in their fur.

  • Oriental Shorthair: Oriental Shorthair cats produce high levels of Fel d 1 protein and have a short, fine coat that can spread dander around the house.

It’s important to note that individual cats within a breed can vary in their allergen production, so it’s always a good idea to spend time with a cat before adopting to see if you have an allergic reaction.

Best cats for allergy sufferers

If you’re looking to adopt a cat and suffer from allergies, it’s important to do your research and choose from the cat breeds that are known to produce fewer allergens.

The best cat breeds for allergy sufferers are those with less of the Fel d 1 protein, which is the primary allergen found in cat saliva and skin.

Popular Hypoallergenic cat breeds include:

  • Sphynx: Sphynx cats are hairless, which means they produce less dander, the tiny flakes of skin that can trigger allergies.

  • Devon Rex: Devon Rex cats have curly hair that traps dander and prevents it from spreading around the house.

  • Siberian: Siberian cats produce less Fel d 1 protein than other cat breeds, which makes them a good choice for allergy sufferers.

  • Ragdoll: Ragdoll cats are low-shedding as well as having lower levels of dander production compared to other cats making them potentially hypoallergenic cats for those with mild pet allergies.

  • Bengal: Bengal cats have short hair and shed less than other breeds, which can reduce the risk of allergic reactions.

However, it’s important to note that no cat is completely hypoallergenic, and even breeds that are known to produce fewer allergens can still cause allergic reactions in some people.
