There is a tremendous amount of information about Siberians and their lower allergen levels, some of it accurate, some of it with numerous inaccuracies. We've been breeding for almost 10 years and were among the first breeders to test our Kings and Queens as well as our kittens. We know that we have low allergen cats and we back it up with the objective lab results.

Most of our kittens will be in the extremely low to very low range and tolerated by by those with mild to severe cat allergies.
