From Spokane, Washington, Bento rose to fame in 2009 when his owner, Charlie Schmidt, filmed the talented kitty showing off his best keyboard skills.

After going viral, the video made Keyboard Cat a celebrity, and he was soon popping up on T-shirts, merchandise and pistachio commercials. He frequented the cat conference circuit, and even shared a manager with Grumpy Cat.

It should be noted that Bento was not the original Keyboard Cat. Schmidt filmed the first cat video in the mid-1980s with his feline Fatso. Fatso passed long before Keyboard Cat went viral in 2007, but luckily Bento was able assume the important role that allowed Keyboard Cat to live on.
