Boogie, a beloved black-and-white feline volunteer at a Chelsea firehouse has died of unknown causes, according to his Instagram account.

“It is with a heavy heart I must share the news of the passing of our beloved cat, Boogie,” wrote his biographer on Instagram.

It is with a heavy heart I must share the news of the passing of our beloved cat, Boogie. Boogie brought so many smiles to this firehouse, neighborhood and even around the world with his silly antics. A cat that was brought in to help with mice ended up becoming a much bigger part of the firehouse family. Boogies passing is sudden and unknown and we are all sad that he is gone. We thank everyone for your love and support of Boogie through his Instagram and coming by to see him. A photo posted by Boogie (@midtownboogiefdny) on Feb 6, 2016 at 8:52am PST

Originally brought to the station to catch mice, Boogie found adoration and fame on Instagram as his caretakers at the FDNY Engine 1 Ladder 24 station house, on West 31st Street between Sixth and Seventh avenues, chronicled his adventures.

The black-and-white kitty, whose serious face and propensity for naps earned him a cool 19,000 followers on Instagram, was five-years-old.

Boogie could often be found standing guard outside the station house, but in his downtime he also enjoyed sleeping, sitting inside paper bags and sleeping. He did not appear to particularly enjoy wearing hats, but often did so for the sake of his followers.

In addition to catching mice, napping, finding Instagram fame, Boogie was also an amorous cat. In June he made headlines when a “Meowinder” (tinder for cats) profile surfaced online. It was not clear on Monday if Boogie had found love before his untimely passing.

As condolences poured in from friends and admirers, a colleague and counterpart weighed in to wish the guardian of 31st Street goodwill in the great beyond.

“We miss you brother,” said Carlow, a firehouse cat employed by the Engine 22 Ladder 13 station house on East 85th Street.
