Fortunately Micheletto seems to have decided that the new place isn't so scary anymore. He's out and about more and he actually ate his breakfast this morning! I was really worried about his not eating - he's not exactly an overweight cat (though he is normally a pig). By last night he was begging for cheese off my pizza so he's definitely better
Cirque, the only reason I found him inside the couch was that AFTER I went to bed and JUST as I was falling asleep I heard him start to cry. I followed the sound to the couch and pulled it partially open. Honestly, I still really don't know how he squeezed in there.
