Good news that you found your snake! I’m always worried sick when a pet of mine or my friends’ might be missing. We used to have budgies (3 in total, 2 at any given time) and unfortunately both of my sister’s flew away and never came back, but on different occasions. My own escaped once, but we soon found her on an outer wall of the house. To my knowledge (I wasn’t in the room when any of it happened), the cause was my sister bumping into the cage while the doors were open. My dog also disappeared from the yard a couple of times, and he has a habit of trying to sneak behind our neighbours’ fences. Thankfully he was back within half an hour each time,whinging at the front doorstep to be let inside! Hopefully you’ll never have to deal with an escapee again, the feeling is terrible.
