His cat Stanley purred on a kitchen chair beside him when he ate breakfast at 24 Sussex Drive.
Harper's first day back at the office after a six-week recess was like most days when the House of Commons sits, including a quick working lunch at his Centre Block desk and meetings with key legislative and executive staff.

Tim Uppal, the minister of state for democratic reform, was left to defend the appointment of five Tories to the Senate.
On the decorum front, NDP MP Charlie Angus appeared to be the only parliamentarian rebuked Monday by the Speaker. He got in trouble for saying Tory MP Pierre Poilievre wore a clown nose.
The most surprising development of the day was NDP MP Pat Martin - the subject of a $5 million libel suit - who participated in a news conference and didn't utter a word.
Martin was forced to get off Twitter in December for calling Conservatives "rat-faced whores."
