The world has seen all kinds of Internet-famous kitties. Grumpy ones, box-loving ones, surprised ones, and even a hipster. Now there’s a new friendly face to join the clowder: Bum, the worried cat.

Bum was rescued last year, and along with his four siblings, he was taken to the San Diego Humane Society in Oceanside, California. His now-owner Courtney Morman, who worked at the shelter, was immediately smitten. While he might look perpetually fretful, Morman told ABC News that Bum is healthy, smart, and "actually super silly and happy."

The tabby is named after Morman’s favorite baseball player, San Francisco Giants pitcher Madison Bumgarner.
