Hello everyone! Todays the big day. I get to try to feed my new snakey girl tonight! IT's already been a week since I got her and I can hardly believe it!

Well, I was recommended to feed her f/t pinky rats by one of the breeders there. (Not the breeder I got her from) but we're having trouble finding them around here and when we do, they're sold out really fast, live ones or F/T ones.
I know one place that's an hour drive +/- and I don't know how the traffic will be either.
She was originally being fed live pinky mice.
So should I just try to feed her a pinky mouse? She kind of looks like she could eat something bigger.

Kind of show how big she is around if that helps any. I can't say how much she weighs since the only way I can measure her is my inaccurate needle-on-the-number food scales that weighs on ounces which I have to convert into grams online. I need to invest in a scale at some point.
Can she eat a different sized rat or a different sized mouse? Or should I just stick with pinks?
