Having a cat while being allergic to them?

My husband and I are just got a 4 month old kitten….while both being fairly allergic to cats. Interestingly enough, we barely even sniffle around her. Sometimes we do notice a couple of welts, but overall I find that we barely have any allergic reactions to her.

I am curious if others have experienced the same thing, and why this could be? Could our prior cat allergies be an issue later on? Normally when I would handle kittens or cats at a shelter, my eyes itch and water and I get welts all over my body. But none of this happened with our kitten. I worry that some day we might become allergic to our kitten and have a reaction so bad that it endangers our lives (yes, I am an anxious person).
