mouser

Larry the cat already serves as 10 Downing Street's chief mouser but there are no plans to introduce pets to tackle the pest problem in the Palace of Westminster down the road.

A number of you also have had the great joy of having the greatest cat ever and the greatest mouser ever.

To me, he was the greatest cat ever, and the greatest mouser ever.

He also developed an antagonistic relationship with the Foreign Office’s own mouser, Palmerston, who has since retired from public duty.

Ralph shuddered at the thought of an electronic mouser sending his family screaming into the snow to freeze to death.
