Hi all!

New here! I'm trying to certify the sex of my checkered garter snake, which I was told was a male when I first got it (it was a rescue, so know very little of its background). I've had two friends, who are both clued up about what they're doing, try to probe it, but the snake clenches and fights like anything and neither of them were happy that they'd got the probe in properly, and didn't want to persist and risk hurting it. Does anyone know the subcaudal scale count for males and females of this species? I have a sneaky suspicion it may be a female...

Thanks!

Andi
