The internet mourns the passing of Mymains Stewart Gilligan (Stewie) the cat, longcat of all longcats. The Guinness World Record holder for longest cat alive has just died at the age of 8.

The cat, who was a staggering 48.5 inches when fully stretched, passed on Tuesday after a battle with cancer.

“Stewie was always very social and loved meeting new people. He has touched many lives, and for that I am grateful,” said Stewie’s human, Robin Hendrickson.

RIP Stewie.
