I think, rather than panicking everytime one sees an ingredients label, the thought process should probably contemplate how much of these chemicals are *truly* included. (meaning, how much of the chemical per unit, quart, serving size or whathaveyou.)
A trace of a chemical might not be lethal or detrimental in any way, versus bathing in said chemical. Take the Baby Shampoo....dri nking an entire bottle might be cause for concern, but as my mother used it on me, and I've used it on my two children and a bevy of pets, and have yet to see/hear of any damage, I think that it's safe to not panic.
As far as the woman linking the FeBreeze to the death of her parakeets...wh at else were the birds exposed to? In all of her daily routines, how did she suddenly link the FeBreeze to the pets? Sounds like BS and a way to make money by suing to me.
