awww do you have a dog at home too? i was growing with both dogs and cats. I had some allergy and always thought both of dogs and cats. My parents like animals and am do i. about 16 yrs ago, my hub begged me to adopt kitties so we went for it and i am shocked that i didnt sneeze cats. Obviously, its dogs. every time i visited my friends while i was in college and still sneeze when they had dogs. now it is very interesting i think i grew out of dog sneezing. But i ll test with dogs later since i wanted to adopt a tiny dog. if you do not have dogs at home then it must be cats.
