Take Herculaneum for instance. A feline guide is available for cat-human encounters. She enjoys human company and is willing to engage in shared meals whenever possible.
The local human cat lovers have ensured that she is neutered and those employed on the site make sure there is regular cat food and water available.
It's a great lifestyle. Dry shelter in the roofed Roman houses, plenty of lizards on the walls to catch, and of course rodents are available.
Best of all, there is freedom in being a community cat, not a house cat. Freedom to roam all round the site. Freedom to ignore tourists or to engage with them.
