Not to go off track, But I think I have the 2 exceptions to that, Bean & Bitey are both in glass tanks with screen tops. When they figure out it's feeding day I have to have my daughter lift the lids off while I feed them, They literally go to the top of the tank to the screens and when daughter removes them and backs up they stretch up to the top of the tank to get their rat, None of my other snakes do that or have done that. Their really polite and calm otherwise.
