I don't think going into the hide caused the bite. I think a cool prey item and a warm hand confused him. I think it's pretty funny, actually. I'm dangling the pinkie right in front of his face. My mammalian mind is thinking, "It's right there! How can you not see that?!" But he's not a mammal, so he uses his heat pits to see. That's why he's confused. To his reptilian mind the prey looks like nothing. My hand on the other hand, that has potential. I just need to learn to see things from his perspective and that's going to take a while.
