New York and the surrounding area is often hit with extreme weather conditions and the temperature can quickly drop below freezing. So it can be very tough if you're a community cat and don't have a warm place to go.

Nathaniel lives in Brooklyn and whilst working from home on a snowy day he realized something was happening outside his apartment window.

It was then that he noticed there was a stray cat pawing at his window, asking to come in – and who can blame her, it was freezing out there.

He immediately recognised the cat as Chunk Chunk, one of the members of a nearby stray cat colony.
