The Siberian is very dog-like. They are loyal cats that will come to greet you with their unique triple purr. This cat breed appears to be fascinated with water and they are likely to drop toys in it. They are a friendly breed, good with dogs, energetic, and smart
The cat was first imported to the United States in 1990, and despite the popularity, the breed is slightly rare in the US. The cat was registered by the Kotofei cat club in St. Petersburg in 1987. This cat, Dorofei, is owned by Russian president Dmitry Medvedev and former Soviet president Mikhail Gorbachev.
Hypoallergenic qualities of the Siberian coat have been noted and commented on for almost ten years. While there is little scientific evidence, breeders and pet owners claim that Siberians can be hypoallergenic to many allergy sufferers. Since females of all feline breeds produce lower levels of Fel d1, Breeders often suggest that allergic families adopt female cats. If you are allergic, it is wisest to check your reactivity directly with the parent cats from whom you plan to adopt a kitten. Many people believe that the breed produces less Fel d1, the primary allergen present on cats.
In 1999 Indoor Biotechnologies tested the fur of four cats for Fel d 1; a mixed breed, two Siberians, and an Abyssinian. The results showed the Siberian and Abyssinian cat fur as having lower Fel d 1 levels than the mixed breed cat. Indoor Biotechnologies cautions that the Siberian levels were still high, and that the mixed breed sample was "exceptionally high." Indoor Biotechnologies warns against using these results to make decisions of pet ownership.
This "test" of fur levels is shown on many Siberian breeder websites as "proof" the breed is hypoallergenic. The sample size is below statistical significance, was submitted by a Siberian breeder, and as mentioned, one cat was found to have Fel d1 allergen levels of 62,813 micrograms (roughly 60x higher than any published professional study).
A not-for-profit association of breeders, (Siberian Research Inc), was founded in 2005 to study allergen levels and genetic diseases in the Siberian breed. As of March 2010, fur and saliva samples from over 300 Siberians have been submitted for analysis, many directly from a veterinarian. Salivary Fel d1 allergen levels in Siberians ranged from 0.08-27 mcg per ml of saliva, while fur levels ranged from 5-1300 mcg. The high-end of these ranges is very consistent with results from prior studies, though the low end is below expected results.
All Siberians tested were found to produce some Fel d1, with the highest levels being found in Siberians that were "Silver" colored. About half of Siberians were found to have Fel d1 levels lower than other breeds, while under twenty percent would be considered very low. Within the low group, males and females had comparable allergen levels.
