Isolating a cat to one area of the home may reduce allergens in other areas of the home, but the allergen will still move about the home in the air and on other soft surfaces like clothing.

• The structure of Fel d 1 (the major cat allergen) makes it “sticky,” and it will attach to clothing and other surfaces resulting in its dispersal into surrounding environments.
• The small size of Fel d 1 allows it to be airborne for long periods of time, making it one of the easiest allergens to inhale or to be moved around the home, even without disturbance.
• Fel d 1 can be found even in homes without cats. Studies have shown that Fel d 1 can be carried on clothing into schools, offices and many other public places.

Some owners may choose to remove their cat from the home altogether in an effort to mitigate their allergies. However, this may not prevent an allergic reaction.

• It can take many weeks for the Fel d 1 levels to sufficiently decrease, and allergy symptoms are not likely to resolve immediately if a cat is removed from the household.12,13
• Cleaning surfaces and soft materials like blankets, couches, and carpets, as well as filtering the air can help reduce cat allergens in the home.

Fel d 1 easily becomes and remains airborne in dander and dust particles and is passively transferred on clothing;2-4 as a result, the allergen can be found almost everywhere including schools, homes without cats, public transportation and public buildings in levels that may trigger allergies in sensitized individuals
