I have 5 parrotts. A cockatoo, blue & gold macaw, yellow naped amazon & a senegal. I have also been using the Ninja 3-4 times a week since the first TSV.
Did not know this about the Ninja pan, and my birds are all in our kitchen/living room combined area. I have not had bird show any sign of a problem. it is a very large, high ceiling area.
My plan is to continue using my Ninja. I do not burn anything in it, and the coating must be heated empty to a very high temperature to release fumes. I love the Ninja!
