Yes I remember - I was about 9 or 10. I had terrible allergies that were annoying like trees and grass, and smoke bothered me quite a bit, but never had an asthma attack until my brother came home with 3 little kittens. It was downhill from that time on. Wishing I wasn't allergic to animals, I love to support their safety and health. Great question. Wishing you a good breathing day. Rebecca (comm advc)
