Yes,
I live in a 3800 sq ft home, with my daughter and her fiancee.
They have 12 cats that urinate, poop and spray all over the house.
There is a constant and very pungent odor and amonia smell throughout the house.
Today, I sprayed about 1500 sq feet of carpet. I ued approx 12 ounces of pet odor elimator; I have asthma, copd and it didn't bother my breathing at all.
People in the level beneath where I sprayed complained that it hurt their eyes, throat, etc. I believe something else was to blame for their symptoms.
My question is: If I have lung problems and was where the spray was used and not bothered by it; Is it likely that people in the basement behind a closed door were actually affecte. They are the type of people who aren't happy, unless they have something to complain about. I am trying to determine whether they were actually affected or just being their normal complainy selves
