We sometimes talk here about shop cats, library cats, bookstore cats, nursery and feed store cats. But have you heard about museum cats? In Russia, it’s common to “hire” cats to work behind the scenes in public places keeping the buildings and grounds rodent-free. And this is even true of some of the most famous museums. The Hermitage Museum, for example, employs 70 cats—a practice or tradition that has spanned over 250 years. I wasn’t surprised to learn that people often drop off unwanted cats at the museum door, but I was surprised to read that people can also adopt one of the cat with the right credentials.
Here’s a site with some absolutely divine photographs

You’ve probably heard of Earnest Hemmingway’s cats. He collected cats with extra toes—polydactyl cats. As the story goes, a sea captain visiting Key West, Florida, where Earnest Hemmingway lived and wrote, gifted him with a white polydactyl kitten. He didn’t have the cat neutered and the rest is history. There are currently around 40-50 mostly polydactyl cats roaming the Hemmingway grounds and museum today. It’s open to the public in case you’re ever in the neighborhood and want to meet a bunch of cats with very large paws. https://www.wideopenpets.com/story-ernest-hemingway-six-toed-cats/
