In the early 2000s we visited the Hemingway estate on Key West, home to around 60 cats.
TBH I saw a few that probably needed to be euthanized.
I can’t imagine the time and expense of taking care of 650.....I guess if they get sick they stay sick.
The Ephesus ruins in Turkey has dozens of well-fed beautiful cats...
They will pose for photos ...
