Self cleaning oven

[Homebody]

Has anyone have/had any issues with self cleaning oven and a ball python in a different room ? I’d like to use it but concern about the fumes

I don't think you'll have an issue. As I understand it, self-cleaning ovens use high heat to reduce food residue to ash that can be wiped away with a sponge (link). I don't think smoke from burnt food residue would be heavy enough to harm a ball python that's in it's enclosure in another room.
