Black cat becomes viral star after invading the pitch during an NFL game

Every sport needs a mascot, but they're usually not of the live feline variety.

But NFL fans were in for a treat at Monday night's prime time game between the Dallas Cowboys and New York Giants when a delightfully Halloweeny black cat stormed the pitch.

And it seemed like the object of its spooky luck-bringing were the Cowboys, who miraculously scored 10 points after the interruption.

American football Twitter was on fire.
