No, no significant news... My friend's wife and I did rent a thermal imager, but we didn't find her. We haven't told my friend because we're worried it would just upset him more. They have flour down and there has been one track going in to a room, so that's good that at least they know the snake is around somewhere, but no one has been able to find her! The three us have pulled the room apart that the track was going into and nothing.
All the windows have screens, they never leave doors open because they have indoor cats, and there aren't any holes going into the wall, so we're confident she's still in the house, but everyone is just super confused on where she could be hiding... My friend says she's due for a shed, so he's worried now that she's just hunkered down somewhere and is waiting that out.
Thanks for asking!! All the help here has been really appreciated!!
