I still vaguely remember the last scene of that famous 1971 film, with Jean Gabin and Simone Signoret, based on a book of the same title by Georges Simenon.
Cats are present in Monaco, albeit not very numerous. One day, the municipality decided to sterilize the street cats, and since that time their population is well under control.
One of these “resident” cats, has chosen as his base a passage under a high speed lane, which I take every day on my walks to and from the office. It’s a lovely dark grey siamese I greet every time I pass by.
