Yes i do. I own two a juvenille desert king and an adult cal king. I have had the cal king for two years and the desert for about 6 months. Still yet to have an escape. I just make sure the locks on the cage are properly shut everytime i put on of my snakes back in its cage after being out, and right before i go to bed at night. I know that most people have escapes and i know i will probably have one eventually too. But it still seems like a careless mistake. You can probably trace the escape back to something you did usually. But then there some snakes that no matter what, they will find a way out.
