Fed my five month old today, he is eating one adult mouse a week right now live. He took it well but only got it's head and neck into his mouth before he just kind of...stopped. He hasn't spit it out and he hasn't gone any further. He's almost motionless, just coiled around it, occasionally shifting slightly. It's been five hours. What's going on? He was so frozen earlier we thought he was dead until we touched his side and he flinched. Any ideas? He's never taken this long. Usually it takes a couple minutes for him to munch an adult mouse, once or twice when he's taking his time it's been up to an hour. Never like this though. He's just paused with its head and neck in his mouth.
