Nikko did not like her or us for that matter for a couple of days -- you would have thought he was a dog with all the growling and complaining that he did.  They now get along just great - although she usually instigates the rough housing and he has a tendency to keep putting her in a bear hug and chewing on her.  As soon as he gets up she is back at him again goading him on to chase her or jumping on his back or nipping at his heels.  I believe that most of this is normal especially that he is still a kitten.  They have even slept in the same chair a couple of times although would probably happen more if she just enjoyed it instead of biting at him!!!!  They never seem to be far away from each other. He mewls around when they separate and lays upside down on the floor -- not sure what to make of that --  sounds like he is calling her.  When we go out we usually put her in the back hall and he has even taken to playing footsie with her under the door.  So needless to say they are becoming fast friends. 
The girls absolutely love her and Roger has a really soft spot for her.  Nikko of course gets lots of attention and is back to purring and his regular routines.  .
