Domestic cats are thought to have been first tamed back around 10,000 somwhere in the middle east. Unfortunately, as this is the cat that makes up the worldwide domestic cat population (almost exclusively) in many regions like Scotland, while reduction in numbers made specific subspecies of wildcat endangered, it has often been hybridisation that has pushed them over the edge.
There is little point in showing a map of the world, as they are found in almost every human population. It is thought that there are at least 200 million across the globe
Domestic cats are thought to have been tamed in Israel, which has unfortunately meant that this species of wild cat is now spread across the globe – many local species of wildcat have become extinct through hybridisation, the British wildcat is just one such example. There are now only pure British wildcats in captivity, and while there are still quite a few living wild in Scotland they have Asiatic wildcat features. This has happened in many places and solutions are not yet forthcoming.
While unfortunate, there is still work being done. In the UK there are plans to clear a peninsular of domestic cats, and re-establish a wildcat population. Only in situations like Scotland is hybridization likely, the most common reaction to a wildcat meeting a domestic cat is for the wildcat to kill the domestic cat. I hope to live to see the wildcat roaming Scotland once more, but we will se what happens.
They are not hard to see if you are in the right place. I have seen them in Africa, take a night drive in almost any nature reserve. Links will be added below.
