UPDATE:
She ate for me for the first time today. I gave her a little over a week to settle in. I prescented for 30 min by placing the box with the mouse in it in her enclosure. Within a minute she was checking out the box and later I saw she was resting her head atop it. When I let the mouse lose it, explored a bit and within a couple minutes she'd bitten its head and had it wrapped up. The whole thing happened so fast. I must say I quite proud! Hopefully, within a few weeks I'll have her on F/T. So my 149 gram snake (less since she had a poo on Sunday) ate an 18 gram mouse on my first shot feeding her. I'm loving it!
