When Mark and I moved back in with my mom I seperated my cats from hers and I also used the feli-away plug in's. It seemed to help. Once we had been in the house for about a week I then started to introduce the cats a little at a time.

One thing that you might want to try is taking a blanket over to the house and getting the scents of her animals on it and then bring it back and let Corkscrew get used to the scents of her animals.

I hope all goes well.
