I would like to mention first that I have no judgment against anyone for any habits they may have.
But... I really believe that exposing any animal or human, who can not make the decision for themselves to leave the room, to incense, air-freshener, cigarette smoke, perfume, etc. is inhumane.
And yes, I do include air-freshener and perfume in this category as I believe most are very caustic.
Sorry.
