I know that itās bad for them but lately since I got my cockatiel things have been a bit stressful and I relapsed on my smoking and vaping habit, I donāt do it around the bird at all but I wanna know how bad is it for them? I do it in the bathroom which has separate exhaust ventilation, Iām wondering is if itās as bad as Teflon (which Iāve removed from my home) where it can kill them from just a whiff from meters away?
