The Treasury recently introduced a third mouser to Westminster - adorable 18-month-old Gladstone.
They adopted him to sort out their mouse problem, but it is quite clear staff have fallen head-over-heels for the domestic shorthair, who began life as a stray before he was taken in by Battersea Dogs and Cats home.
As we walked around the Treasury with the cat, staff stopped to give him a stroke, and he seems to love the attention just as much as they love him.
Gladstone currently lives in an office where six very willing members of staff have added cat care to their daily duties. Armed with cat toys and open laps they pamper him until he is allowed outside to hunt for mice.
Battersea gave care advice to the Treasury staff, and his carers seem to be very happy with their assignment. "He's been lovely to have", said one Government staffer.
"He has improved my job satisfaction", said another.
But they were quick to reassure worried readers Gladstone isn't about to tank the economy - he isn't disruptive. "You can still get on with work - and if you're in a bad mood you can play with him in your lunch hour and he will cheer you up!"
Other members of Treasury staff have taken advantage of this aspect of owning Gladstone, too, regularly visiting him on their lunch breaks and after work.
Is this the most pampered cat in Britain?
It certainly seems so - members of staff and people who visit the office donate to his feeding fund, which was originally started by senior Treasury staff members.
The cat is also free to pad around the offices - and staff keep track of him using an app called Pod. A glance at their phone, and they can see exactly where in the offices Gladstone is.
To ensure the pampered puss is kept in toy mice, catnip and food, the staff run regular fundraising drives. They are even thinking of making their annual quiz £1 more expensive to enter in order to get money in the kitty for Gladstone.
Sadly, the cat has not had an official meeting with Chancellor Philip Hammond, as it is recess. Mr Hammond could be taking the time off to play with his dog, who is rumoured to be moving into Number 11, much to the dismay of local mousers Larry and Palmerston.
When The Telegraph asked whether Gladstone is set to get involved in Larry and Palmerston's notorious scraps, it was met with a resounding "no".
The Treasury cat won't be venturing on to Downing Street, but will stay in the Treasury quads for his outside time.
"Letting him on Downing Street would interfere with his work - it is his job to catch mice. Of course, he will still get ample time outside" said a Treasury staff member.
After his first week in office, the mouser still had not caught any mice. This is partly because he's been settling in, and partly because he hasn't been allowed outside yet.
However, this doesn't mean he isn't sorting out the mouse problem. The mere smell of a cat can deter mice from nesting, and reduce the amount scuttling about the corridors.
This is good news for Number 10's chief mouser, Larry, who is reportedly terrible at catching rodents.
Mice scuttle around multiple Government departments, nibbling food and startling staff and MPs. "It's only the old Government buildings, like the Foreign Office and Treasury which are having a problem with mice", said a member of Treasury staff.
"The new buildings don't need a mouser."
This means we aren't about to have a Government overrun by cats.
MPs and their staff have, however, been clamouring for a cat because of the mouse problem in Parliament. Stella Creasy MP in particular tweeted when Gladstone's appointment was announced that the catless situation in Parliament was 'unfair'.
Staff have also been defacing posters advising how to minimise the mouse problem by writing: "GET US A CAT".
It's no surprise they are jealous, or that Gladstone is so spoiled; The Telegraph can confirm that he is an absolutely gorgeous cat.
