[Mara Montalbano] It's this cop's job

to keep the British Prime Minister safe,

and, while he's at it,

help her cat stay dry.

[Classical music.]

Larry is the resident cat

and 'mouser in chief'

at 10 Downing street in London.

He mostly wanders around outside,

greets the guests,

and helps the guards
keep watch over the place.

He enjoys the occasional back rub.

But,

not from everyone.

But when rain starts to fall,

Larry heads home,

and since 10 Downing

doesn't have a pet door,

he has to wait

for someone to let him inside.

He gets lucky when visitors
show up, or leave;

but, on this day,

the officer standing watch

took pity on this kitty,

and knocked for him.

[Upbeat music.]

Others have done it in the past,

and it just seems like

it comes with the territory
on this job.

Larry was adopted from
a rescue shelter,

by former Prime Minster
David Cameron, in 2011.

And he stayed behind
when Cameron left office.

These days, Larry is roommates

with Theresa May,

and seems to enjoy

'photo-bombing' her,

as she negotiates
Britain's exit

from the European Union.

While his country is
trying to get out,

Larry just wants to get in.
