Air Quality: Animal Dander


Big Idea: Animal dander can worsen asthma.

Talking Points:

  • While cats and dogs are among the most beloved pets, our furry friends can pose a threat to the health of people with asthma.
  • Animal dander is a protein in warm-blooded animals’ hair, skin flakes, urine, feces, and dried saliva. Warm-blooded animals include cats, dogs, and rodents like hamsters and guinea pigs.
  • Dander can get caught in the animal fur and can cling to walls, floors, furniture, bedding and clothing.
  • Research has found that asthma is worsened when people who are particularly sensitive are exposed to cat and dog dander.
