Live Science reports that cat dander may be harmful to adults with any type of allergy – even if they're not specifically allergic to cat dander.

‘Exposure to cats is more of a problem than was thought,’ says study author, Susan Chinn of Imperial College, London.

Exposure to cat allergen increases bronchial responsiveness (the propensity of the airways to constrict), and Chinn says that the clinical implication is that all allergic people ‘might benefit from reduced cat exposure.’

If you have cats in your home, consider investing in Allergy Armor Ultra bedding, an air purifier, and a HEPA vacuum cleaner to reduce your exposure to cat dander.
