This study may be true, and I am no lover of cats, having one that pukes regularly on our carpet, but I do remember reading of another study not too long ago which said that children who grow up in homes with dogs and/or cats have better immune systems and fewer alleries than those who aren't around pets. It may seem counter-intuitive, but living in a sterile environment causes more allergies than living in a filthy environment. What we need is more aerosolized dried cat spit in the air.
