But on 10 April another couple spotted a black cat curled up in a nearby pine forest. He was friendly and wore a collar, and they took it to the Ofunato Health Centre. After several days nobody had claimed the cat, so the centre put an announcement in a local paper. It was when an employee was taking a photo of the cat that he noticed the Yamagishi name and number in faded letters on the collar.
