I came home tonight around 10:30pm and fed my animals, and I noticed that they hadnt come out of their nest yet. I saw that the male was on top of the female and he had the back of her neck in his mouth and was clamped around her with his legs. He was also moving his head back and forth in a hypnotic fashion tugging on her neck. To get rid of any possibility that he was sick or anything, I opened their nest and got them out, and the male just held on to the female tightly as she jumped around the cage. I can only assume that they are FINALLY starting to mate. It will be very interesting to see their mating instincts. I think I have seen one so far.
