Osborne, the Royal Court Theatre Cat

Osborne started working at the Royal Court Theatre when they had a mouse problem and caught 25 in his first week.

Osborne had an excellent first week at his new job. This black tomcat had just joined the Royal Court Theatre company in London, which was temporarily located at the Duke of York's Theatre while their actual venue in Sloane Square underwent extensive renovations. They had a mouse problem at the temporary location, and Osborne tackled it like a pro, catching 25 mice in just his first week.

The Royal Court closed for a major redevelopment in 1996, and during the renovations, the company moved its productions to other theatres around London. That’s when Osborne got adopted. His first responsibility seemed to be mousing, and judging by catching 25 mice in his first week, he was really good at it. When the Royal Court finally returned to their renovated Sloane Square building, Osborne became a part of the company too, and he moved back with everyone else.

At the Royal Court, Osborne patrolled the corridors, hung out with the cast and crew, and was supposed to stay in the Green Room during performances. But "supposed to" was the important part. Jackie Orton, the costume supervisor, remembered that Osborne sometimes managed to sneak out during shows and make an unplanned appearance onstage.

And there is photo evidence showing at least one theatrical outing. Osborne was photographed onstage during the Royal Court's 1997 production of Eugène Ionesco's The Chairs at the Duke of York's Theatre, the same temporary home where he'd been adopted to deal with the mouse problem.

His name was pretty suitably theatrical, too. People thought he was named after playwright John Osborne, but some also suggested that Ozzy Osbourne might actually have been the inspiration. Either way, he found his perfect place.

After years at the theatre, Osborne eventually retired to Camberwell with Orton. Adjusting to life at home was a bit of a challenge. "He couldn't bear to be alone after all the drama of the theatre," Orton later remembered. After being around actors, crew members, rehearsals, and audiences for so long, Osborne found a quiet house much less exciting.

He passed away on Halloween, October 31, 2013, at around 18 years old. By that time, he had an impressive theater career for a cat: he was a mouse catcher, a backstage member, and even an occasional performer. But catching 25 mice in his first week was probably his most productive run.
