Hi Pili
I know that you've received a few responses already but I wanted to tell you my experience with moving. I suggest that you let your cats enjoy a room in the house (like a spare bedroom) for a few days. Keep their litter, food, favorite toys, blanket, etc in there with them. And you visiting them often of course. This way they can get use to the sounds and smells of the house before they get the full run. This has worked wonderfully for me.I've heard horror stories, that when people move their cars hide for several days. So this is just a suggestion that has worked great for me. It did not stress my cats out at all and I didn't have to worry about them getting into anything or running out an open door while I was moving, etc. This way they got use to the house sounds, etc. Good luck!
