Alien Big Cats, Big Black Cats, Phantom Panthers—they are known by many different names and have been encountered not only in the UK but also around the world for decades, if not centuries. Often dismissed as hoaxes or hallucinations, these creatures are very real to those who encounter them. Any proof of their existence has been elusive until now, where new DNA analysis has revealed that they may actually be genuine creatures. However, DNA does not explain the supernatural elements of these experiences, and we will discuss some of the unusual incidents of high strangeness associated with these enigmatic beings. We will also consider the new wave of UFO disclosure and contemplate the clandestine nature of extraterrestrial beings and their connection to occult rituals.
