Animal charity Battersea Dogs and Cats Home have suggested a possible pet for the Prime Minister - a three-year-old called Crocket.
Head of cats, Kirsty Walker, said: "We have some great cats here at Battersea and any one of them would make a great family pet for the Camerons, not to say ward off any unfriendly rats.
"We are confident Battersea could offer a terrific successor to Humphrey - a coalition cat - the Prime Minister could be proud of."
