The European wildcat, Felis sylvestris, lives almost unnoticed in our forests and is one of the least-known wild animals at our latitudes. Previously the species was widespread in Europe outside of Fennoscandia. Now only isolated populations remain after severe persecution and excessive hunting. A recent status evaluation of the European wildcat in Switzerland suggests that a residual population of a few hundred animals exists in the Jura. It cannot be determined whether this is a remnant population or one made up of immigrants.
