Thank you so much BMD. I hope he behaved himself in the car but if his purrfect behaviour in the metro was any indication, he was probably fine.
I confess that I called the clinic just to check that he was OK. They like him alot and I know he is in good hands (sniff). He calmed down so much over the past few days, really an angelic cat, with his little voice, in the morning we would greet each other with a head butt, Tibetan style. Wish I could've kept him, but this is next best.
