Animal dander is tiny, lightweight flakes of skin shed by pets like cats, dogs, and rabbits. These flakes can easily become airborne and settle on surfaces in our homes. Dander can also include proteins found in saliva, urine, and feces of animals, which can trigger allergic reactions in some people. When inhaled or touched, animal dander can cause symptoms such as sneezing, itching, and respiratory issues for those who are sensitive. Regular cleaning and grooming of pets can help reduce the amount of dander in your living space, making it more comfortable for everyone, especially those with allergies.
