April 4th,2011 we arrived at Vienna,via Amsterdam. When I saw Elsa and Michael at the airport,it was a luggage claim corner, I found their two cages were clean. Cats were also clean. They didn't look tired. I thought someone of KLM took good care of them. It was thankful. We picked up two cats with other luggages and nothing like a passport control about my cats was requested. We went to the hotel and stayed there for a month, looking for an apartment to rent.
