Thanks for all the responses! I'm still leaning towards moving them last- the main reason being is because the new place is going to be utter chaos for most of the morning. Plus we have furniture going in every room, and I'm not sure where to "store" the kitties while it's all getting moved in. From what I've read here, it seems that both options seem to work out ok. In the evening, when everything is moved in in the new place and all our helpers have gone, I think they'll be a little more relaxed with just us...we'll still keep them confined to the "kitty" room with all their stuff for a few hours before letting them out to explore their new pad.
