I have never had an issue with introducing a cat to it's new home. I think the biggest factor is us. If we enjoy coming home and relaxing, the cat will get the hint very quickly. The home is where the heart is, or should be. I think the cats know this.
Missey was young when she came home and the greatest place to introduce them to is that great big warm bed. They have always loved it. Once they are in and comfortable, calm then they start the great explore. Happens with every kitten I have had.
