A member asked:

Can you suddenly get an allergy to cats when you never had reaction before?

A doctor has provided 1 answer
Dr. Lee Perry answered

Yes: Allergies are very unpredictable, and it is possible to develop an allergy to something (cats) later in life, even if you've never had a reaction before. I would recommend skin testing to provide a more definitive answer to your question.
