Swiffer Wetjet Pet Death Email Rumour
I guess they are all in a big conspiracy to kill our pets.
This "friend" forwarded you a hoax email that has been going around for years. If this was a true danger to our pets, we would have known of it long ago. When the melamine made it's way into our dog food, it didn't take long before vets and other experts started putting two an two together and found out the truth behind what is going on.
Once again, Bless your heart.
And go ahead and call me any name you want, I will consider it a badge of honor.
