Doesn't look like a lot of action on the forum, but here's a quick follow-up:

I got 3/4 feeding on frozen thawed small whole pinks on the first attempt. I crumpled a small paper dixie cup, put a pinkie mouse inside, put the cup into an empty clear plastic deli cup, put a boa in the deli cup, then put all 4 cups with all 4 boas into a dark closet overnight. I checked them late the next morning 3/4 had eaten.
