There are some truly great threads about various "traps" you can concoct to try to catch a hungry snake. Yes, look in warm places, up as well as down. We just had a rugged 6 weeks of missing our Takala. I have no idea how she squeezed out, but she did. We tore the living room up, to no avail. She finally surfaced, after 6 weeks...wrapped around my alarm clock, 18 inches from my head. Don't give up, and don't quit looking. I hope your story eventually ends happily!
