Jet black cats do exist through- the British Black shorthair is
disqualified in cat shows for any white whatsoever- the breed was
created by breeding black street cats to black street cats until such
a time as any white was bred out.

That aside he/she is not a feral. At some time the cat had a home and
is making it perfectly clear they would like another one...yours

If you had even tried to pet/pick up a true feral after three days you
wouldn't be writing to this list- you'd be in hospital haviing skin
from your butt grafted to your face to cover the mess.,
The cat has chosen you..get used to it!
