When I was in my late 20s, I developed a severe allergy to cats. Anytime I visited friends or family members with cats, I would have terrible sneezing fits. As the years passed, the reactions became worse. Not only did I have the sneezing, but my eyes would become red and itchy and I would even have trouble breathing. And then I tried this product, and after 3-4 months I noticed my allergic reactions around cats began to get better. When I would go off the product, the allergies would come back. It's been 8-months now and I can finally visit my friends and family members and not worry about any allergies to their cats. Do you know someone who might be interested in a product like that?
