How is it that some people build up a tolerance to some allergies like cats?

    Experiments with both eggs and peanuts have shown that exposing a person to a very small amount of an allergen, then increasing the level of exposure very slightly each day, can eventually lead to them being able to tolerate normal levels of the allergen with no allergic reaction. The levels of immunoglobulin E in the individual’s body, an antibody produced when exposed to an allergen, decline to very low levels during the treatment.

    Presumably, exposing oneself to cat dander for a small period, then increasing time that each day could help reduce the allergic reaction. But doctors recommend that severely allergic people should only undertake such experiments in a laboratory setting.
