Hello, and I'm sorry to hear of your loss. Teflon is a big no-no for all birds, as well as cleaning supplies, candles, air fresheners, etc. I don't quite understand what is left as far as teflon is concerned. It should NEVER be used at all. Why don't you research as much as you can while you are waiting to get another bird. There is always something new to learn.
I'm glad you joined our family. Please stick around and keep posting. You'll make lots of friends here.
