When we bought and moved to our house from an apartment, we took RB Butterscotch to the house to get aquainted. That was a bad move he ran upstairs and shook. So we only stayed like 5 mins tops and went back to apartment.
Moving day we kept him in one of bedrooms until the last load. In carrier he went and over to the house. We put carrier out on front porch so he could see us. After unloading which was under 2 hrs. I opened the carrier door and he didnt want to leave because he was to cozy. Couple mins later he came out and walked around saw familar things and was just fine.

RB Butterscotch always had to see what was going on even when we've had work done on the house. Bathroom remodel I put him in carrier in livingroom so he could see what was going on. We had a new back door put on he had to be in kitchen in his carrier to see what was going on.
