i let my guys eat as much as they want. they seem to know when they are full even if they haven't eaten all of the crickets i provide, so i just take out whatever they don't eat once they lose interest. it is definitely easier to handle them with someone else present. eenie is a little calmer and i feel pretty comfortable handling her on my own, but meenie is a little more jumpy and wild, so i have only handled him when my fiance is there. meenie will jump from me to him, dash up around his shoulders, at which point i coax him back onto my hand, and then we do it all over again until he calms down enough to jump onto jeremy and just hang out.
