British big cats, sometimes referre to as ABCs, short for Alien Big Cats or Anomalous Big Cats, phantom cats or mystery cats, are non native big cats, possibly predatory, said to be roaming the countryside of the British Isles. For many years their existence has been debated and many scientists have dismissed them as fake. To this day they are thought of as an exotic part of British wildlife by some and as an urban legend by others. Those sighted are often claimed to be "panthers", "pumas", or "black cats".
