Sorry, I don't have a decent picture of the plug. I've tried, though and will probably have the chance to try again soon

. I took my blue
T. ordinoides out of brumation about a week ago, and the male is all over the female. He's like her shadow. It's not full-on mating, yet, but I think he's gonna pop once she starts to shed! Then I'll try to get a better picture of the plug. BTW, you know it only lasts 1-3 days, right?
I think side-views might be most helpful, but it can be difficult to tell overfed snakes from gravid ones on pictures. It's easiest to confirm by feeling her stomach/abdomen. Put your thumb on her back, and your fingers underneath her. Then give gentle pressure so that you can feel about 3/16" into her as she crawls back into her cage. You should be able to feel the lumps if she's gravid, but she has to be fairly relaxed.
