Speaking of super tiny...Does anyone have a solution for young snakes sneaking out through the gap between the top of tub and the top of the rack? This little guy got out twice on me, luckily as I was watching him, and currently a desk calendar I slid under the tub is doing the trick...

Here's a photo of the setup, and animal plastics sterilite 1960 rack. Anyone have experience with this issue? How fast will this little guy bulk up so it's no longer an issue even without the calendar?
