What is the point of the lids anyways?
I saw someone near me use that for his colubrids and never understood why...
Is it so they wont spill the water? If so why not put two bowls in each other just like you would stack tubs and then glue the bottom bowl to the tub with some very sticky glue and when u need to change the water just pull the water bowl in the top out and replace it... This way it cant spill and your snakes wont die.
