How to Tell If You Have Cat Allergies

Up to 30 percent of people have allergic responses to cats and dogs, with cat allergies being more common, according to the Asthma and Allergy Foundation of America. Cats shed dander which can trigger allergies. Pet hair can also contain other allergens such as pollen. When you develop an allergic response to a cat, your immune system tries to ward off what it considers a foreign invader. Proteins from a cat's saliva or shed skin can cause a reaction, resulting in uncomfortable symptoms.
