I had a adult ball python along time ago. he just ate and the enclosure i had him in was a good size had 3 doors and i forgot to latch the top and he got out of here co uldnt find him for 2 weeks. He was in the closet 2 feet from his enclosure sleeping luckly i was up at 2am when i was cause he was on his way down the hall. and my redtail boa i forgot to close her tank good one night find out the next morning she was gone and found her 5feet away under the couch. Now i always double check my enclosures and locks weither i took them out or not.
