Th cats appear to be getting excellent medical care, they aren't bothering anyone, most of the visitors there are just as interested in the cats as their are in Hemmingway and they have more of a right to be there than anyone else. They are descendants of HIS cat. The government should just leave them alone. Let's not worry about immigration or terrorism, let's worry if a cat is sitting on the floor of a giftshop or not. My 2 cats sit around and don't bother anyone.
