I haven't had any regular escapes, not in my old house or on this house. However,... When i lived with my parents, i had all kinds tricks to make sure i could Never forget to lock an enclosure. Did not want any cats eaten, and snake keeping is pretty controversial hobby here.. Any escape would not be beneficial to the hobby. So i added pin key-chain alarms to the locks, if the pin was out if would beep until you put it back in so i couldn't forget to lock. Worked really well but did not prepare me for the following.
I had 1 wooden enclosure, just for show in my bedroom. I kept my beautiful 4 foot purple albino tiger male in it. One night i heard a load creaking noise.. i thought he knocked over a branch like he did often. The next morning i wake up to see the top of the enclosure broken, the entire ventilation strip pushed out! Snake nowhere to be seen. My door was closed, and there was no way to get out of the room. I searched for him but couldn't find him, i suspected he had hidden inside the bed which i could not get to. So i kept the door closed at all times, 2 days later i wake up because i hear a funny sound.. and i look up to see him hanging from my ceiling lamp
