Big cat hunters are investigating 'cougar' sightings in South West Australia.
Vaughan King is flying to Perth with a crew of documentary film makers to hunt down big cats that are said to be roaming the Harvey area.
Vaughan is working with a local farming family who believe they heard sounds of a cougar last week- which apparently sounded similar to a girl screaming.
A nearby family member claims to have witnessed a big cat around one year ago; having lost many chickens to what he thought initially was foxes.
The farm owner stayed out at night in order to catch the cougar in the act and believes he spotted something which looked similar to a mountain lion at around 2.AM.
Since the sighting, the farmer told Vaughan that he had heard unusual big cat calls numerous times.
