I would take one room and make sure everything is set up there. Put their favorite beds, food dishes, and litter box there. When you bring them home I would keep them in that room for an over night until they calm down.

This is an excellent suggestion and one which I will definitely try.

Thanks catcrazylady !!

Hopefully all will be well in no time. At least now they will have a staircase to run up and down, and a second bathroom to hang out in..heck that's half the reason we chose to move was to have more room for the cats to be playful in, lol!
