Pet dander refers to tiny, lightweight flakes of skin shed by furry pets such as cats, dogs, and rabbits. These particles can easily become airborne and may settle on surfaces in homes, making them a common allergen for many people. Dander can also include proteins found in saliva, urine, and feces of pets, which can contribute to allergic reactions. People who are sensitive to pet dander may experience symptoms like sneezing, runny nose, or itchy eyes. Reducing exposure to pet dander can involve regular cleaning, using air purifiers, and grooming pets frequently. Understanding pet dander is important for managing allergies effectively.
