Introducing cats together in a new home

I am moving in with a friend who has three cats two brother and sister and one female. My cat is a 3 year old male. We are all moving into a new home and the cats have never met or been in the home. We are wondering how to best introduce them so none of the cats can declare the house their territory. Thank you

Hi and welcome 

For the best results, it's recommended that you follow the steps in this article exactly: http://www.thecatsite.com/a/introducing-cats-to-cats

Be sure to go slowly and fully complete each step to the cats satisfaction before moving to the next one.  If you rush things, unfortunately, what often happens is that you need to start over entirely.

Good luck with your move!
