Once a famous cat to the British Museum, it became the "Chief Mouser" in the Cabinet Office, the UK government. This cat named Larry was an inhabitant at 10 Downing Street, where the British Prime Minister resides. He was expected to control the mice population of the area. It is intriguing that the office of Chief Mouser was most of the time a caretaker for stray cats or abandoned felines.
There was, for instance, Mike. Everyone knew who Mike was because of his years-long tenure as an official mouser for the British Museum. While the work is not catching mice, per se, the feline symbolizes the value placed on a good cat in a museum's day-to-day existence.
Mike became a darling of the visitors as well as staff. His work was not only to catch pests but also to make the atmosphere in the museum slightly charming in his own way. His interaction with the staff was too excellent, especially having a reputation of detesting some specific people in society, especially females, and being extremely cranky when it came to food.
Mike's fame spread far beyond the museum. Many articles were written about him, and he became some sort of celebrity within the British media. His personality was part of his attraction—while he was a skilled mouser, he also sported a rather unique set of quirks and characteristics. When Mike passed on, the museum decided to pay tribute to him. A memorial was erected in his memory to commemorate the feline pal of the British Museum at the Great Russell Street entrance.
