British scientists say they have discovered how cats trigger allergies in people, raising hopes for a possible cure to the feline-caused affliction.


Researchers at the University of Cambridge say they have found a protein in cat dander — or dead skin cells — that interacts with a chemical in the human body to cause allergy symptoms, which can range from itching and sneezing to asthma attacks.


The discovery could be used to create a drug, delivered in pill form or through an inhaler, that researchers say could effectively block the allergic reaction. Watch the video report above.
