Number 10 has denied claims that Larry the Downing Street cat is disliked by the Cameron family following speculation in a new book.
David Cameron hailed volunteers at Battersea Dogs and Cats Home but struggled to hold on to one little dog.
While Blair and Brown kept their blows behind closed doors, the current residents of No 10 and 11 are seen brazenly brawling in the street.
David Cameron has again insisted his family loves Larry the Downing Street cat despite being unimpressed by his mouse-catching skills.
The Prime Minister denied the claim in Matthew d'Ancona's book In It Together that the cat was unpopular, and said: "I'm very keen on Larry, my family love Larry, and now we've got Freya as well, the Chancellor's cat."
He told Sky News Radio: "I think where this story came from is I was once rude about Larry's mousing abilities.
"It is true that he once sat on a chair in my study at Number 10 and this mouse ran across the floor and Larry just lifted his head and had a look at it and did absolutely nothing."
The Prime Minister has moved to dispel rumours that he and his family do not get on with Downing Street's resident cat Larry:
I can set everyone's mind at rest in the #SaveLarry campaign. He and I get on purr-fectly well. The kids love him too .
An officer beckoned Larry the cat into Downing Street as he waited patiently on the steps outside.
Larry the Downing Street cat has survived the reshuffle.
He has retained his job as Chief Mouser to the Cabinet Office - despite only catching one mouse in a year.
