>>10-13-18 tonight he ate 2 live pinky mice, pretty aggressively. Seems like he just enjoys the thrill of killing. I'll continue to attempt to get him onto frozen next week.

If it is eating two at a time, wait 10 days until he is good and hungry, feed him a live and a frozen thawed at the same time. maybe the live will create a feeding response for the F/T.
Good Luck
