Fel-d1 Levels

About half of Siberians have naturally low levels of feline allergen (Fel-d1). All cats, including Siberians, produce some allergen.

Saliva testing is more reliable than fur tests, but cats that do not produce enough saliva for accurate analysis can be tested using fur.

Several catteries have worked with Siberian Research, Inc to establish reference ranges for allergen levels in Siberians. In general, many Siberians test lower than other breeds.

Saliva test range in Siberians: 0.5 mcg - 30 mcg
Fur test range in Siberians: 7 mcg - 820 mcg

Kaleriia Wings: We have tried several times to test saliva levels in Kaleriia, but she does not salivate enough to obtain a stable sample. She has very low allergen levels in fur, and has never caused an allergic reaction with a cattery visitor. Her kittens place very well in homes with moderate to severe cat allergies.

Asthera Jenika: Test levels were higher than we initially expected, though a re-test by Asthera Siberians who bred her was somewhat lower. Even so, we could not keep her in our breeding program.

BirchGrove Kiska: Allergen tests showed levels higher than our other queens, and Kiska caused moderate to severe reactions in several cattery visitors. She was spayed and given to a home without cat allergies.
