My 16 year old niece has itching, watery eyes and stuffy nose when visiting my house, we have 2 cats. After 2 visits, she came to the house and I questioned her on her symptoms. She said it happens when she holds the cats. I asked her to hold the cats and she was excited that she had no symptoms for the duration of the visit and beyond. She had this reaction to cats as a young child and this is the only thing that has made a dramatic difference in her reaction to cats.
