Cute indeed - and welcome to the site!
3 weeks shouldn't freak anyone out too bad as far as skipped meals go - certainly worse has been suffered with no ill effects. Glad he is in more attentive care though! I wouldn't dare nod off with one of ours out - just too many irretrievable places they could get to and not be seen again. Did you give him any acclimation time after the relocation?
Good idea on scoping the show for f/t - paying shipping on those orders is always a hard pill to swallow at ~$35 per.
