You don’t often hear about public memorials for cats, let alone thousands of people participating in them, but the fact that tickets were gone for P-22’s “Celebration of Life” within three hours speaks to the special place the mountain lion had in the hearts of Californians.

The famous puma, who was euthanized in December after he was suffering from an infection and was hit by a car, called Los Angeles’ Griffith Park home, and that’s where the celebration will be held at noon Pacific (3 pm Eastern) on Feb. 4. It’ll be held at The Greek, the outdoor amphitheater more commonly associated with rock stars, although one could argue P-22 was a rock star in his own right.

P-22 was the subject of books, movies and music festivals during his 12-year life, and his face adorned t-shirts, murals and street signs asking people to be careful while driving around the Griffith Park area, where the big guy ranged. He was the most famous mountain lion in an ongoing study of his species, and was easily identified by the radio collar around his neck.

P-22’s “origin story” was equally fascinating. Born in southern California in 2010 or 2011, the fearless puma migrated north, crossing several of the busiest and most dangerous highways in the world before he settled in Los Angeles. His nine-mile home range was the smallest ever recorded for a member of his species.

Separately, there’s an effort to honor the late puma with postage stamps featuring his famously derpy visage.
