I recently visited Clervaux in Luxembourg to research a new supernatural thriller. In my book, Clervaux has more cats than one can handle. In reality, though, there are only a handful of them. When I visited Clervaux for the first time fifteen years ago, I met the famous Clervaux castle cat, a cute calico that greeted all visitors at the entrance to the 12th century whitewashed castle. Today, that cat is no longer there. However, if you walk along Rue Schloff which surrounds the castle, several other cats will greet you. The cats above were spotted at Rue Schloff 7 and 9.
