My stupid kitten drank the snake's water this morning... what should I look for?

I swear, with kittens, you can’t turn your back for a second.

I was cleaning out the snake’s cage, and I put her water on top of the desk. I turned back to the cage to wipe it out and when I turned around, the kitten was on top of the desk drinking the water.

That was close to 12 hours ago… but I’m not sure if there is really any need to worry, or what I should be looking for if it’s going to make her sick.
