My son had a 4 foot Ball Python in its tank in my pole barn for the summer. Eight days ago he fed it one mouse. It managed to escape and is in the pole barn someplace. Three days later he noticed it missing. It is a large pole barn (50' x 100') and is impossible to find it. The building is full of trunks, farm equipment, tools, etc, and etc. There is no water in the building. How long can the snake survive in this situation. What do you recommend to be done? Is there any possibility it will survive the winter in Pennsylvania if it is not found? I would appreciate anyone giving me information along this line. Would the Ball Python be more likely to remain on the concrete floor, or on shelves that are built around the inside perimeter. Would it likely climb to a rafter?
