My retic pushed the corner of his locking tub open enough to squeeze out of when I was resealing his cage. I got really lucky and found him under an old swivel chair that was in the corner. He was curled up under it on the floor sleeping lol. When I tipped the chair up and saw him, he just raised his head, looked at me and then laid back down and went back to sleep haha. I scooped him up and he didn't even bother moving. I put him in his cage and he crawled into his warm hide and went back to sleep. He was unaffected by it but I was traumatized as my thoughts were what if he crawled in the laundry room and got inside the dryer, washer or forced air heater. That would have been a major issue.
Funny part is I have put all my snakes in the same kind of locking tubs as I got one for each snake for if I have to move them in a power outage and none have ever gotten out. Caesar was the only one who did. He did take a huge piss in the tub though as when I opened it in the morning, all I saw was piss soaked pile of paper towels and his hide lol. Guess that gave him more incentive to push the corner of the lid up.
