Number 10 has been in a right cat flap following claims that Larry the Downing Street cat is disliked by the Cameron family.
Following allegations in a new book that the six-year-old-feline was little more than a public relations prop, a "savelarry" hashtag quickly took off on Twitter.
GlobalPolitico wrote: "The radical anti-cat agenda of this government is revealing itself."
Cumbrian Labour councillor John Burns tweeted: "Is there no end to David Cameron's victimisation of those who cannot speak up for themselves?"

Ladbrokes: Larry the cat is 1/2 favourite to outlast Cameron in Downing St #savelarry-- Ladbrokes Politics (@LadPolitics) September 28, 2013
Judging by the number of cat pics on my Twitter feed every day, Cameron has just lost the election... #savelarry-- Tom Flynn (@tom4camberwell) September 27, 2013
Downing Street moved to dismiss suggestions in Matthew d'Ancona's In It Together that the cat was unloved.
A spokesman said: "Totally untrue. He is very popular with everyone in the building and we all get on purr-fectly well."
Larry was re-homed at Number 10 on February 15 2011 by animal charity Battersea Dogs And Cats Home after a rat scuttled across the doorstep of the PM's residence during a live TV broadcast..
But the cat's initially lackadaisical approach to his mousing duties led to speculation that his days at No 10 could be numbered.
In August last year Downing Street confirmed the lazy puss had finally recorded a kill.
