Animals of the UK - 2. The cats of the flats
There's an old cobbled block of flats in Stoke Newington and although no more than 200 people can live there at most, there are 12 cats. Most of whom never leave the area of the flats, so they act as if they own it.
Which they sort of do. There's a complicated society of these cats, complete with social hierarchy and insecurity. They have replicated human society but, being cats, their society is even more neurotic. It's a salutary lesson to us all - if it all goes to the cleaners then, like in Doctor Who this series, we may end up cannibalising ourselves and turn into these cats.
