Are they Hypoallergenic?

Most of what you will read on the internet about the Russian Blue breed being hypoallergenic refers to their reduced production of the Fel D1 protein, but there are several other unexplored proteins that can cause people to have an allergic reaction. They are far less common, but they exist nonetheless. Even with the reduced amount of Fel D1 protein, the Russian Blue (like any other breed) is not guaranteed to be non-allergenic. There is no truly non-allergenic cat. 

​

Fel D1, concentrated largely in cat saliva, is thought to be the major allergen responsible for human immune hyper-reactivity. ​The following paper in the Journal of Allergy and Clinical Immunology examines Fel D1 and Fel D4 levels in cats: jacionline.org/article/S0091-6749(18)31175-8/fulltext

​

If you or your children have an allergy, please do not take it lightly. You may experience symptoms and may need to return your kitten after your family has become attached to the kitten and the kitten to you, which is highly stressful for all involved​

​

Because we want permanent homes for our Russian Blues, we will consider homes where one or more adult family member has cat allergies ONLY if they are willing to take the necessary precautions and medications if needed.
