Wildcat

A wildcat in the narrower zoological usage is one of the closely related wild Felis lineages resembling the domestic cat. Current Cat Specialist Group taxonomy distinguishes the European wildcat, Felis silvestris, from the Afro-Asiatic wildcat, Felis lybica, and from the domestic cat, Felis catus. Older literature sometimes grouped several of these lineages within a broadly defined Felis silvestris. A feral cat is a free-living domestic cat, so living without human care does not alone identify an animal as a wildcat.^[ref]

Genetic markers can investigate ancestry beyond outward resemblance. A 2007 study by Carlos A. Driscoll and collaborators assessed 979 domestic and wild cats, comparing microsatellites and DNA sequences from mitochondria. The sampled domestic lineages clustered closely with Near Eastern wildcats. The paper's own subspecies names should be read in its historical classification, rather than silently replaced with a modern species list.^[ref]

The comparison separates two questions: what ancestry the sampled animals share, and what taxonomic rank to assign each lineage. Hybridization with domestic cats can further complicate identification, making one coat pattern or one inherited marker an incomplete description of an individual animal.

The Afro-Asiatic wildcat, Felis lybica, is a wild species of Felis distributed across much of Africa and parts of Asia. The Cat Specialist Group distinguishes it from the European wildcat, Felis silvestris, and the domestic cat, Felis catus. Some older work treated these regional wildcats as subspecies of a more broadly defined Felis silvestris.^[ref]

Its relationship to domestication has been investigated genetically. The 2007 comparison of domestic and wild cats found close clustering of domestic samples with sampled Near Eastern wildcats, rather than with every wildcat population equally. In that paper, the relevant lineage was named within the older subspecies scheme.^[ref]

This supports a particular ancestry relationship in the sample; it does not make a present-day Afro-Asiatic wildcat simply a lost pet. A feral cat is a domestic-lineage animal living independently of direct care. Current behavior and genetic ancestry should therefore be recorded separately when studying encounters or hybridization between the populations.

The European wildcat, Felis silvestris, is a wild species of Felis associated with European and neighboring forest populations. In the Cat Specialist Group's classification it is distinct from the Afro-Asiatic wildcat and the domestic cat. The common word wildcat in older literature can refer to a broader collection of regional lineages, so the scientific name must be read in context.^[ref]

Hybridization with domestic cats complicates identification. Nuclear genetic markers and DNA inherited through mitochondria need not tell exactly the same ancestry story. The 2007 wildcat comparison explicitly marked individuals whose nuclear clustering and mitochondrial lineage differed. That makes a single coat pattern or one inherited marker an incomplete account of ancestry.^[ref]

For an illustrative comparison, two striped cats could have similar appearance while differing in their inherited marker combinations. Appearance remains useful for observing animals, but testing population ancestry requires a stated set of markers, reference samples and classification criteria. Geographic location alone is also insufficient to turn every free-living domestic cat into a European wildcat.
