Where's the best place to find a robot cat? The library, of course

You know that feeling you get when something's become a thing and you had no idea? Well, I felt that way when I discovered that everyone -- apparently -- was saying "delulu." Today, though, I'd like to present you with a new thing -- to me: robot cats in libraries. I first came across it when I heard about Bandit, Percival, and Mr. Pickles. Instead, these three are robot cats that live in the Eugene Public Library in Eugene, Oregon.
