Hypoallergenic Cat Breeds: What the Science Really Says

By Tailwisp Editorial TeamUpdated October 20, 20264 min read

Few topics are as full of marketing as hypoallergenic cats. Breeders and sellers advertise special breeds that promise sniffle-free ownership, and allergic cat lovers desperately want it to be true. The honest answer is more complicated, but there is still plenty you can do.

What causes cat allergies

The main cat allergen is a protein called Fel d 1, made in the sebaceous glands of the skin, the salivary glands and the anal glands. Cats spread it when they groom, and it clings to fur, dander, furniture and clothing. It is very light and sticky, so it floats in the air and travels on clothing, which is why people with allergies can react even in homes without cats.

Other cat proteins, such as Fel d 4, also cause reactions in some people.

Is any breed hypoallergenic?

No. Every cat produces Fel d 1, though amounts vary by individual. Studies suggest that unneutered males produce more than females and neutered males, and that allergen levels vary widely between cats of the same breed. Some research found little difference between breeds. Marketing claims that a breed is allergen-free are not supported by evidence.

Breeds that some allergic people tolerate better

Some people report fewer symptoms around certain cats. These reports are individual, not guaranteed, and are best treated as a reason to test, not a promise.

Shedding matters less than you might expect, because the allergen is mostly in saliva and skin. A cat that sheds little spreads fewer hairs, but dander and saliva remain.

Test before you commit

1. Spend time with the specific cat, several visits of an hour or more, without taking antihistamines first.
2. Handle the cat, including its fur and face, and sit in its home.
3. Wait a day or two, since reactions can be delayed.
4. See an allergist. Testing confirms the allergy and the severity, and an allergist can advise on treatments.
5. Ask for a trial adoption or foster period, if possible.

If you have asthma, take extra care, since allergens can trigger serious attacks.

Ways to reduce symptoms

• Keep the bedroom cat-free. You spend a third of your life there.
• Use HEPA filters in main rooms and the bedroom.
• Vacuum often with a HEPA vacuum, and wash bedding weekly in hot water.
• Choose hard floors and washable covers over carpets and upholstery.
• Bathe or wipe the cat, if the cat tolerates it, using methods recommended by your vet. Frequent baths can dry skin, so ask first.
• Brush the cat outdoors, or have someone else do it. See how to brush a cat.
• Wash hands after petting and avoid touching your face.
• Neuter the cat. Neutered cats produce less allergen.
• Consider medical treatment, such as antihistamines, nasal sprays or allergen immunotherapy, as advised by your doctor.

New approaches

Researchers are testing ways to reduce Fel d 1, including special diets with an egg-based antibody ingredient and vaccines. Results so far are mixed and incomplete. Ask your vet before using any new product, and do not rely on one product to solve allergies.

Alternatives to living with cats

If symptoms are severe, ask your allergist whether it is safe to own a cat. In some cases, the right course is to choose a different pet or to admire cats from afar. Living with uncontrolled asthma or allergies is a risk to you, and surrendering a cat later is hard on the animal.

Asthma and allergies

Allergy and asthma are related but not identical. A person with cat allergy may have sneezing, itchy eyes and hives, while a person with allergic asthma may also wheeze, cough and have chest tightness. If you have asthma, make sure it is well controlled and discuss cat ownership with your doctor before bringing a cat home. Keep rescue medication available, and watch for symptoms in the first weeks, when exposure is highest.

Children and early exposure

Research suggests that early exposure to pets may lower the risk of developing allergies in some children, though results are mixed. This is not a reason to bring a cat into a home with a child who already has a diagnosed cat allergy. Talk to your pediatrician or allergist if you are unsure.

Choosing carefully
