Jeff ate tonight and is getting braver. He's now coming out to the acrylic door(s) on his tank when he smells food. He hasn't taken after his two boa siblings and started nailing the doors yet, but he happily devours his F/T prey (now an adult mouse) when offered.
It's nice to see him getting more adventurous and growing into his own.
Don't get me wrong, eating was never an issue for him, but he had been a little shy about exposing himself and generally would strike from a hide (peeking out). Now he's got much of his body out of his favorite hide when strikes.
