You are getting some good advice.

I really want to emphasize keeping the kitty SAFE and SECURE during the move. People will be tired, not paying attention, and kitty could possibly escape. So, if you are not boarding her, then, please make signs that are HUGE "do not open door, kitty inside", and post it on the door she will be staying in.

I would probably have figured out where you want her litterbox to be, and place it there, NOW. (well, when you get there). And, she will have a litterbox in the room-bathroom you are confining her. Then, over a few weeks, you can pick up the one in the room she is confined to, as she will have found the other one.

Remember that your 'new' house will prolly have some hidey hole places you aren't familiar with. In my house, the basement has some places that were VERY unsafe for the herd. I didn't really **think** about them. So, remember to look like a kitty would, and cover up things...

Good luck, and welcome to PT!
