Good news for cat people! A team of Swiss scientists is working on a vaccine dubbed "HypoCat" that will relieve allergies to our feline friends. Most people are allergic to Fel d 1, a protein in cat saliva, sebaceous glands, and skin. Swelling and itching are common symptoms, and it can even trigger asthma attacks. The HypoCat vaccination has shown very promising results thus far. Dr. Lori Gil, via Bustle.
