Something I forgot to mention -- you may look into using something like Feliway that releases calming phermones to help lower her anxiety and make the transition smoother. You can find it on amazon and it comes as a diffuser, wipes, or spray. I've used it and had great success with my very stressed kitty when we moved. The diffuser is definitely the best, you can leave it in the room she is confined to. The wipes and spray definitely has their place, though (think: cat carriers prior to vet vists!).
