For bird owners (or anyone),
It is very important for you to know about Teflon in your kitchen that can affect your bird's health that lead to death. Teflon is one of many things that you use such as waffle iron, some pans, and some others on the stove.

I am pretty sure that the Teflon is also bad for human because some things that we do not know where the cancer come from so it is probably one of them on the danger list. Like lung cancer, skin cancer, etc. In 20 years later, a big news might says that it is very harmful to human. Most companies, who make Teflon or other brand, do not give a damn about customers except profits.
