Well, like the others said, she would adjust given time. It could be 2 days or 2 years. Or she could be another Minette who under no circumstances wanted to be around another cat. I swear if we even had her the remainder of her life, she'd have lived happily in one bedroom so long as it meant to never be nose to nose to another cat ever again. I never minded going into her room twice a day, and always felt comfortable knowing she got love because my daughter slept in there every night.

I truly worried what would have happened if Minette was still here while my daughter headed off to college. My main question to myself was whether or not I'd be able to give her enough one on one time AND then go into another room and give the same one on one time to the remainder of the cats. If you are comfortable with the idea that she might be isolated for an unkown amount of time.... which might possibly be forever, and you are willing to let her go as slow as she wants to go with the introductions, then you'll be fine.
