For years, common knowledge believed that cat fur caused allergic people to sneeze and cough around cats. However, researchers recently discovered the real culprit: cat saliva.

Apparently cat spit sticks to a cat’s fur and when humans come in contact with the fur, the saliva on the fur triggers the allergic reaction. That means you can hug your cat all you want just as long as you don’t touch any part of the cat that has saliva on it, which means there’s very few parts of a cat you can actually touch.
