The way i see it is that the snake gets cold(because he's not in his tank) so it goes to sleep for a while. Then if you wait 3-4 weeks they start to get really hungryand go on a wonder round.
Just make sure that the room he was last seen in has the door closed all the time.
Best of look to you! Just try and be patience
