The Siberian Forest Cat is known for being hypoallergenic for many people. So if you have allergies there is a good chance that you can own a Siberian. Most Siberians have a low occurrence of a glyco-protein enzyme called FEL d1 in their saliva.

Many people with sever cat allergies find that they can own a Siberian and have little to no allergic response to their cat. It is recommended that you test your allergies with a live Siberian, or request a fur sample to allergy test with from the parents before you buy . For the allergy sufferer there is now a very good chance, you can share you life with a Siberian.
