Are Siberian Cats Really Hypoallergenic? An Honest Answer

People ask me this question almost every day: are Siberian cats hypoallergenic? As the breeder at Siberian Legacy Cats in Ferndale, Washington, I want to give you the honest answer, not a sales pitch.

The short answer

No cat is 100% allergen-free. But Siberians are one of the breeds that many allergic people tolerate far better than other cats. Siberian cats naturally produce lower levels of Fel d 1, the main protein behind most cat allergies, and many of my families tell me they can finally live with a cat without constant symptoms.

What actually causes cat allergies

Most people assume cat hair is the problem. It is not. The main trigger is a protein called Fel d 1, which is found in saliva and in the skin glands. When a cat grooms, the protein ends up on its fur, and then spreads through the house as dander and shed hair.

That means shedding and allergens are different things. A cat can have lots of fur and low allergen levels, and the other way around.

Why Siberians are different

Siberians are an old natural breed from Russia. For many generations, a lot of Siberians have produced less Fel d 1 than the average cat. Because the breed developed naturally in a harsh climate, it also has a strong immune system and a thick triple coat.

Levels still vary between individual cats. Within one litter, one kitten may produce noticeably less than another. That is why I breed for low allergen qualities as well as temperament, and why I added a male, Simba, from low-allergen lines in 2022. I would like to start testing my breeding cats for allergen levels.

What I tell allergic families

• Spend time with the cat first. If you can, visit by appointment and sit with the kittens or adults for an hour or more. This is the best test.
• Tell me about your sensitivity. Mild, moderate and severe allergies are different. I will give you my honest opinion on whether a Siberian is likely to work for you.
• Talk to your doctor. If you have asthma or serious allergies, ask your allergist before you bring a cat home.
• Be patient. Some people find their symptoms settle after a few weeks as their body adjusts. Others find they react. I cannot promise how you will respond.

Tips for keeping allergens low at home

Even with a low-allergen cat, small habits make a big difference:

• Brush your Siberian a few times a week, ideally outdoors or by someone who does not react.
• Wash bedding and throws weekly in hot water.
• Use a HEPA air purifier in the bedroom and keep the cat out of that room if you can.
• Vacuum with a HEPA filter and wipe hard floors rather than sweeping.
• Wipe the cat with a damp cloth occasionally to remove saliva and dander.
• Wash your hands after petting and avoid touching your face.

Kittens or adults?

Adult Siberians have fully developed allergen levels, so you know what you are getting. That is one reason I recommend considering one of my retired breeders if you are very sensitive. You can read more on the adult Siberian cats page. Kittens are more of a guess, because levels can change a little as they grow.

Does coat colour matter?

You may read that certain colours are lower allergen, but there is no reliable evidence for that. Please choose your kitten for temperament and for how you react to the individual cat, not by colour alone.

My honest recommendation

If you have mild to moderate allergies and have struggled with other cats, a Siberian is well worth a visit. If you have severe allergies or asthma, go slowly, talk to your doctor and spend time with an adult cat before you decide.
