In Switzerland the wildcat is only found in the Jura. For centuries it was considered as virtually extinct, but in the last 20 year, the forest cat – as the European subspecies is also called - is experiencing a renaissance presumably based on the populations from adjacent France.
The forest cat is adapted to cold winters, but is sensitive to long lasting closed snow cover which impedes hunting mice. Therefore in the low mountain as the Jura, the wildcat population can fluctuate greatly, depending on the winter conditions. Increasingly mild winters seem to favour the wildcats return.
