i switched the snakes from live, to pre-killed, and tonight i tried frozed and thawed. i put the snakes in the boxes, and let them roam around for a moment. i used tongs and made the mouse do a little dance. roswell took a moment, but he got it and swollowed it down pretty fast. roo got it even quiker. as soon as she smelled it she jumped, and got it. they both had no problems taking the f/t mice. i hope they will take them from now on.
