Not sure... who drowned them?

I am unsure. I didn't notice, wasn't watching.
And then i came to clean the pool, and there is a garter snake all drowned.
Maybe it was Mother Nature. I hear she can be quite the bitch.

Or maybe there is a bully snake pushing snakes into the pool.

Most snakes that I know, including Garter Snakes, are pretty good swimmers. I'm surprised you found one drowned, unless it got exhausted and then sunk...

I am unsure if it got exhausted or had something to do with the chlorine.
But, it indeed drowned. Which was very sad.

I was thinking about that too. Don't worry, there's more where that came from.
