what the?

My milksnake drinks its water and spits it out! I think because I have a bowl that cant be knock over or splashed out. But the bowl was dried out of water and the sand was all wet. so do snakes spit out the water to cool the sand down or just to make a mess?

maybe his mother was a spitting cobra.

does your snake eat well?

Maybe it's soaking and splashes it out. Is your water bowl bigger than the snake or if the snake was to go into the water bowl could it's mass be what is causing the water to overflow?

What kind of a water bowl is splash proof? I'd like to see a pic if possible.

If the snake soaks and leaves the bowl, its body would be wet and that could get onto the substrate. (Why are you using sand? An absorbent substrate is better than sand.)

I doubt the snake is spitting up water, unless it is ill. If healthy I doubt it very much.
