My male normal got loose a few months ago due to my stupidity of not latching the lid appropriately on his tank. He got loose at night in my bedroom while I was asleep. Luckily he couldn't fit under my door and I always keep the door shut when I go to sleep. I found him in my bathroom that is in my bedroom. He was hiding in base board heater all curled up. I was very fortunate that he did sustain any injuries. Most of the time these snakes can be found very close to their enclosures. Please don't beat yourself up, it happens to the best of us. Do not give up searching, you will find your snake. Good Luck my friend!
