The Siberian cat breed is known to be hypoallergenic (lower allergen levels, not allergen free). This means that most Siberians do not provoke allergenic reactions in people who otherwise have reactions.
Fel d1 Allergen Taken from: http://kittentesting.com/?page_id=11
The majority of cat allergies are caused by a small stable glycoprotein called Fel d1. Each allergen in a species is given a number when it is identified. The first house cat allergen identified was labeled Feline domesticus allergen 1, or Fel d 1. Fel-d1 is produced by lacrimal, salivary, sebaceous (oil), and perianal glands.
Fur length does not increase or decrease the amount of allergen produced by salivary and sebaceous glands, thus evenly hairless cats can be highly allergenic (allergy provoking).
In 2006, allergen levels were measured in 420 adult un-neutered Siberian cats. Half of the Siberians in the study had found to have lower levels of feline allergen than other domestic breeds. Roughly 15% of the cats had exceptionally low levels of Fel d1, with both males and females found in the lowest group.
We test Fel d1 levels in all our breeding cats. We can arrange to have your kitten tested prior to purchase at your expense. Cost of testing is $250.00 through a Virginia laboratory. For more information: http://www.kittentesting.com/
We’ve learned that Siberians all have some degree of allergen levels, and the human body needs time to adjust. In most cases, the first 2-3 weeks after your kitten comes home your body will be adjusting and you may have various allergy symptoms. After a month your symptoms should be gone, or at least significantly diminished. When your Siberian goes through its moult/shedding season, your allergies may temporarily flare up again. In general, you will need to have a Siberian in your house for at least a month, to give your body time to adjust to your cat’s allergen levels before you know for sure how you and that particular Siberian will get on together.
With so many people affected by allergies, it is wonderful to be able to offer beautiful, semi-long coated pets to families who previously thought they could never be pet owners! Even if you are not affected by allergies yourself, visitors often are and are often surprised to find they have no reaction to the Siberian cat.
The following suggestions can reduce the buildup of Fel d1 and other cat allergens in the home.
Routine bathing removes a large amount of allergens present in the fur. Your cat will still produce the same amount of Fel d1 allergen, but the amount in the home will be lower. Weekly bathing your cat reduces household airborne feline allergen levels by 45%.
Place washable throws on any area your cats like to sleep. Include couches and chairs as well as climbing stations and cat beds. Wash all throws weekly in hot water, detergent and borax to remove and deactivate allergens.
Frequent vacuuming rugs and soft surfaces reduces allergen levels. Air out the house after vacuuming, and damp mop hard floors and wipe hard surfaces. When possible, replace carpets in bedrooms with washable hard flooring.
Clean and change litter boxes frequently to reduce Fel-d1 and other allergens. The highest concentrations of many allergens are found in the litterbox. If at all possible, place the litter box outside, or another room that can be vented to the outside. Young kittens get dust on their coats from powdery litters, which tracks irritants and allergens into the house. Try different types of litter.
People with mild – moderate cat allergies may be able to allow their cat in the bedroom. Individuals with severe or dangerous allergies should have an allergen-free room for sleeping. Keep your cat out of the bedroom.
High efficiency particulate absorbing (HEPA) filters are high-efficiency air filters, and are good at removing very small particles like Fel d 1. Running a HEPA filter and keeping your cats out of the bedroom can reduce air borne allergens in your bedroom by up to 50%.
