I'm going to look real hard when I get home. My wife has torn the snake room apart and can't find her. But she did have an idea which scares me. In that room one of the grates that sits of the ductwork for our central heating is a little too small. It's a few inches too short to cover the entire hole that leads into the ductwork.
If she got in there then god only knows where she could wind up. I don't even know if she could get out of it if she did get in there.
