I've been thinking about getting some more snakes in the future, which will make it necessary to switch from glass tanks to plastic sweater and/or shoe boxes. I've seen several plastic containers that look like they'd make great enclosures except for one thing -- I don't trust the lids. They always seem to be too loose and move up and down just enough that a rat snake would have no trouble slipping out when I wasn't looking. Is there a certain brand of sweater boxes that has a tighter lid than the others, or do people use clips? How do people get around this problem?
