Question
My 7 year old son has had wheezing since he was a toddler but only used the inhaler when he had a cold. A few months he went to my mother-in-law’s for a few days and his asthma was triggered along with watery red eyes. I’d never seen him like this. Turns out he’s severely allergic to cats. The cats are leaving her home and they are repainting some of the walls. What else needs to be done so that he doesn’t get triggered? Is there a period of time it takes for the dander to be gone?
Answer

Once the cat is removed from the home, it will take up to 6 months for all of the remaining cat dander allergen to be gone.

There are things you can do in your home to decrease and remove residual cat dander allergen.

  • Thoroughly clean the home, including steam cleaning of carpets.
  • If possible, replace old carpets with hard flooring material.
