Did you read my rambling post? I've tried assisting 3 times now. He doesn't bite down and doesn't coil. Last time I tried, about an hour ago, he just sat there with the mouse in his mouth. For about 5 minutes. I've tried getting his teeth hooked but he still shakes it...
Need to push the mouse further down towards the back of the throat. Some will latch on right away some need the mouse further down.
