Ohhhh, yeah- I should really have taken into account to size of the rings in comparison with the pinky- silly me. It's just that it looks like an adult snake to me but it must, in actual fact, me very small to fit in between the rings like that.
P.S. There's one thing I don't like about pinkies and that's the way their insides show through their skin- very nasty- but it makes them easy to just pop if your snake is a fussy eater and has a taste for blood.
