Bunny....
When a kingsnake is wandering in its cage it is doing one of the following 4 things:

1. Looking for a mate.
2. Looking for a meal.
3. Seeking the right temps.
4. Seeking the right humidity level.

Unless it has mites...that will cause them to wander alot too.....and crawl on their backs and do strange things.......

And.....You cannot overfeed a king if a good thermal gradient is provided......When I say good I mean 90F hot spot and 70F or lower if possible cool spot (air temp).......When they are wandering or in the cool spot conserving energy....feed them....If they refuse then it may be the time of the year...Winter or breeding season.........But always question your husbandry and adjust......
