There are two somewhat hilarious ironic aspects to this. First, Squrrl is not the one known for disappearing/running off. He's always been more of a 'homebody', though happier to go some place with his Humans in the cars than Smudge was. So he disappeared...

Except, he disappeared into the House. Of course.

And yes, they all understand WORK TO DO, NAO, KTHX. On the occasions when I get back from Hospital late and may stop to feed all livestock on the way in, rather than getting the Bros (thus, yanno, a Night Off for them) Squrrl is quite disappointed. What? NO WURX? ONOES!
