Why Do I Have A Cat Allergy If I Was Born Into A Cat Home?

[Yavuzen]

Is this just unlucky or what do you think?

I was born with a cat in my home and had no allergy til about 14 years after I was born.

What's up with that? Had Cat(s) my whole life why did this happen?
I understood what you said, but are you saying this was not that uncommon or not that unlikely to happen.

Or is it just bad luck considering I was born into a cat home?

there are receptors in your genes which are subject to change with time. Just as your hair and eyes could change color in your lifetime, your allergies can change as well. For example, when someone is lactose intolerant, it is because a receptor in their genes is being blocked and cannot accept lactose from milk or other dairy products, if that receptor is to get "lifted" they will no longer suffer from being lactose intolerant. I was never allergic to cats and now my eyes get all itchy and sometimes i start sneezing, this was really bad for a while but nowadays it only gets that way after i have spent a few days in a row at my boyfriends house because he has 2 cats. hope that helped
