Manx cat
After Peter III's death, the Lieutenant Governor of the Isle of Man, Sir Ronald Garvey, suggested that a Manx cat be his replacement, and sent Peta to the Cabinet. She was noted to be lazy and loud, and not toilet trained. By 1969, some civil servants had tried to remove her from Cabinet, but this did not happen, because of the suspected bad publicity that this action would incur. She was not heard of again, until a reply to a member of the public in 1976 revealed that she had retired to the home of a civil servant. Her successor was Wilberforce, who became the next Chief Mouser in the 1970s.
