Sort of: The less exposure, the better. If he is genetically predisposed to develop a cat allergy, there is enough cat dander in the environment that he probably will. However, the more exposure he has, such as going for daycare in a home with cats, or - worse - bringing a cat into the home to live with him, the more likely he is to develop a cat allergy, and the worse the symptoms will become. ...Read more

Sensitization: You have to see the substance at least once (maybe many more times) to prime your immune system into recognizing it. The next time you are exposed after that, your immune system will see the substance and start an allergic reaction. The likelihood of this happening depends on one's inherent predisposition to develop allergies, as well as the route, amount, and duration of exposure to the substance. ...Read more
