Mine all have a tendency to use their water bowls as hides and spill EVERYTHING! So I finally decided if you can't beat 'em, join 'em. I now use shallow, small dog water bowls, the kind that are spill proof. They also double as good hides because the hollow ring underneath. Now both owner and snake are happy. Well, owner sort of. They end up spending all their time under the water bowls so I never see them!
