Larry attempted to put up a fight, but after Freya landed a paw on his neck he was forced to flee back to Number 10.
Witnesses said that relations between the two cats have been strained since Freya usurped Larry from his role of prowling the corridors of power. Larry was appointed Chief Mouser to the Cabinet shortly after he was brought in to deal with the rodent problem on Downing Street in February last year.
Swiftly earning a reputation for napping rather than ratting, it took him 18 months to record his first confirmed kill.
Then last month it emerged that Larry had been victim of a Government reshuffle as the Prime Minister sacked him as Chief Mouser to the Cabinet.
Mr Cameron, who admitted Larry was a ‘terrible mouser’, had apparently grown tired of his lethargy. He is thought to have found Larry dozing in the Number 10 study as a mouse ran across the room. The Chancellor’s tabby Freya was then given the role of Chief Mouser.
Freya, who arrived in Downing Street in June after going missing from Mr Osborne’s previous home for three years, is thought to be an altogether more tough and street-wise predator and has been described as a ‘lethal feline killing machine’.
