Product review (1 stars): So sad.
No were on the package does it say TEFLON is dangerous when heated. It gives off a gas that is deadly to birds. On new years eve while cooking in my oven with a liner in, my two parrots dropped dead within a minute of each other. I  SUGGEST YOU  STOP SELLING these liners until the manufacturer places a LARGE warning about the danger of TEFLON.  PLEASE PASS THIS ON TO THE MANUFACTURER and save heartache to other bird lovers. So sad.
