Keyboard Cat, the cat who played the keyboard, has sadly died.
The internet sensation, who was also known as Bento, reached nine years of age and passed away on 9 March 2018.
Bento wasn't the original Keyboard Cat - that was Fatso, who found fame in 2007 after quirky VHS tapes shot in 1984 were uploaded to YouTube (shown above).
But Bento stepped up as a worthy reincarnation of Fatso, who died in 1987, and took up the title in 2010.
Owner of both cats Charlie Schmidt posted a tribute to Bento, epic and moving in equal proportions:
The internet is in mourning.
We were privileged to know Keyboard Cat, one of the earliest memes and internet animal heroes.
