Westminster is not its usual hive of activity over the summer weeks - but one resident has not been kicking his heels.
While his boss sunned himself in Spain and Cornwall, Larry the Downing Street cat has been earning his keep.
The five-year-old-feline, who was brought in last year to help curb a mouse problem at Number 10, has finally recorded a kill.
"I can confirm that the cat did kill a mouse this morning," a Downing Street spokesman said.
Larry joined the staff at Number 10 in 2011 after a rat scuttled across the doorstep to the famous building during a live TV broadcast.
His apparently lackadaisical approach to his mousing duties to date had led to speculation that his days serving the PM could be numbered.
But his new found success may be enough to secure the former Battersea Dogs and Cats Home resident a reprieve.
The timing was particularly apt, coming on a day when one of Mr Cameron's senior MPs publicly questioned whether he was "man or mouse".
The No 10 spokesman quipped: "The only dead mouse in Downing Street is the one Larry caught this morning."
