The bride and I recently returned from a fine week with friends in Key West, where we were fascinated with the Ernest Hemingway Home and Musuem and its array of cats, many of which exhibit the polydactyl trait (6 toes).
Image credit Gary, of a painting hanging in the house, I believe in the main upstairs bedroom. I did not note the painter or date.
This gray was quite friendly. The rules of the road for the Hemingway Home tell guests not to pick up the cats, but petting them is just fine. They'll exit if the petting gets too much.
Mostly they just lay around, people-watching.
