Put a little male that I had cycling for a couple weeks in. He cruised around and then hid under the wood slab on the cool end. Female starting vibrating her tail rapidly (ala rattlesnake or colubrid) and then she raised it and squirted all this juice out. Here's a pic of her tail:
Then, about 2-3 minutes later, the male comes screamin' out of the hide spot and starts to court her. He was all over her, much like a milksnake or kingsnake male. Here's a pic:
Within about 4 minutes or so, there was penetration. They were so placid too. I even moved the male's upper 1/3 to get this pic. Once they are breeding, you can't do anything that'll make them stop. If they bail when you touch the cage, then they aren't breeding. During courting, the female can get spooked, but during mating, I feel that you can move most pythons around and do pretty much whatever you want. They seem to be in a trance, much like when boas give birth. Pic here. Couldn't get my arms in to lift the tail to get a pic of insertion as the litter dam is too high. You get the idea though. Female is 16 months old. I'm not getting my hopes up. This is more of an excercise to turn the males I have into MACHINES. LOL!
