After two months, if you still want pets, bring the
pet into the house. Measure the change
in your symptoms, and then decide if the change in your symptoms is worth keeping the pet.
A frequent and very thorough cleaning of your house is important during this time because animal allergens are sticky and adhere to walls, clothing and other surfaces. Remove all pet items from your house, vacuum or wash all surfaces including walls, and remove or steam clean your carpets.
