No matter if you have other pets or not, you should have your new kitty in a small space set up just for them.  It is their safe zone.  If you have other animals, it is especially important to keep them seperated for the first few days, maybe even a week.  The new kitty will be getting used to the new smells of their new home and its people while the other pets will get to know the new kitty by smelling it through the door.  Cats learn alot about each other through smell so let them take a few days to do this.  They will adjust to one another without ever having seen each other.  The same goes with dogs.  Let them get used to each others smell through the door before a face to face introduction.

   After a few days, confine your other animals in a room and let the new kitty explore another room in the house.  They will smell the other animals and leave their scent as well.  You can also let your original pets visit the new kittys room, just make sure there are no face to face meetings yet. 

  The kittys might play footsies under the door and this is a good sign.  If they aren't hissing through the door, you may crack open the door a little so they can see each other.  If they both seem curious and unafraid, a face to face meeting would be the next step.  If they hiss and swat, just close the door and give it more time.

 Another idea is to put the new kitty (after a few days) in a carrier and take them into the main part of the house.  If you are sitting on the couch, put the carrier on the couch with you and let the other animals sniff and look at the new kitty.  There may be some hissing  but both the new and old kittys are safe.  If the hissing becomes more urgent or growling and swatting occurs, put the new kitty back in their room and try again tomorrow.  It can be a slow process but it will be successful if you are persistent.  Don't rush it.  A bad first meeting between the new and old pet can be hard to get over.

When they do have their first face to face, they may hiss and swat a little to establish dominance.  Let it happen, just watch carefully.  If it appears that it is escalating into a full blown fight, put the new kitty back in their room and confine the other kitty as well.  They need to start learning that you will not tolerate that behavior.  After a cool off period, try again.  Remember, be patient.
