I too was so relieved to hear you had found Boo , i felt sick to the stomach for you, i know how i would have felt ,were it my cats.
I hope you are re-united very soon, dont worry i am sure he will settle in just fine.
I wanted to wish you a fond farewell from Aoetearoa, but im a bit late, however, maybe you will return for a visit someday again, I hope your new life back in the states goes well, and i am looking forward to hearing about your Wedding.
