Where does pet dander come from?Updated 7 months ago

Pet dander is tiny particles of skin that are shed by animals with fur or feathers. All animals, including cats, dogs, birds, and rodents, produce dander. When an animal sheds its skin, tiny scales called dander are released into the air. Dander is made up of proteins that are found in an animal's skin, fur, and saliva.
