The water bowl is right next to the door of the cage for easy removal and replacement. It's an AP cage with sliding glass. She was half out of the cage when I was trying to grip her, and so only about a third of her made it into the cage. Absolutely this was my fault, though, as I was as freaked out when she shot off and totally butterfingered it. Basically, only the front of her made it into the water bowl and the rest shot out of my hand, slapped into the side of the cage, and flopped onto the floor.
I'll keep an eye on her motion and give her a feel up. Normally I wouldn't handle her today as tomorrow is a feeding day.
This is absolutely my problem. I'm so damn nervous about it that I make mistakes like this. And it's tough to get them out of their hides (which is stressful for them and me, as I don't want to reach my hand into a hole with teeth, and they don't want to be disturbed). I'm sure I'll calm down when I'm more used to this, but I guess the value of the snakes freaks me out more than the bite even. Half the time my hands are almost shaking. So clearly I'm the one who needs acclimation.
THANK YOU EVERYBODY FOR THE RESPONSES. I felt like the biggest dingus on earth when I dropped her.
