Leave it to a cat to make an international move as stressful as possible. Though we anticipated that she might not go willingly and locked her in the house that morning, she slipped out at some point when I opened the door. And, from some excellent hiding place, she watched as the entire neighborhood mobilized to find her (probably as much to stem my hysterical flood of tears as for any other reason).
We had to leave without her, but neighbors and friends saved the day promising to feed her, check in on her, and bring to the US for us when they come in a few weeks. Someone sent this picture of her on our porch the next day, looking for all the world like she owns it.
