We moved 3 weeks ago. The girls did great, before we finally moved in, we brought them here very regularly to show them around and get them used to the place, we gave their potties a place so they got used to "their potty corner"
The day we moved in we took care of their belongings first ( food bowls/water dispenser - toys - crate - blankies & our bed ) our bed is their bed lol ... i kept their treats at hand so that i could "praise" them for using their "new potty corner" (they are litterbox trained)
They adapt very quickly, so there's no need to worry
Good luck with the move!
