We are not doctors, and much less experts in allergies, so we advise that in cases of severe allergies, you always consult a specialist.
Here we talk about what is our personal experience in the coexistence of this breed and some cases that we have had with people who suffer from allergies to cats.
In our house, we usually receive visits from friends, and of course, we have friends who are allergic to cats. One of our friends, has strong symptoms of allergy to cats, and this prevents him from entering houses with cats, since within minutes of coming into contact with the environment they itch, cry and his eyes become red, sneeze, and breathing becomes difficult. Well, despite this, he can spend hours in our house, and he does not suffer from any allergy symptoms. However, if you pet cats, you have some mild symptoms of itchy eyes.
Other allergy sufferers, who have also spent long periods of time at home and have stroked the cats on several occasions, have not presented any symptoms,
We have also had visits from families with allergic children, who had no allergy symptoms with our cats during the visit, and in the hours after.
So, although we cannot guarantee that Russian Blue does not cause allergies, we are certain that the symptoms are markedly reduced compared to other breeds. However, we always advise consulting with the specialist, and being in contact with the cats before making the decision to adopt a Russian Blue.
