“…As in previous samples (Schauenberg 1977;Piechocki 1990), ITL is the most reliable character in differentiating wildcats and domestic cats (CD = 2.4). The clear gap between ITL distributions in our samples is even wider than previously observed (Braunschweig 1963). The intestine of the domestic cat is more than 40% longer than that of the wildcat (mean 2080 mm, SD 111 mm to mean 1440 mm, SD 126 mm).…”

GermanyÕs large population of wildcats (Felis silvestris silvestris) can be clearly distinguished from domestic cats on the basis of morphological characters. However, an examination of 71 specimens from Thuringia also illustrates the risks involved in using only a few such characters. The most reliable tool for identification in the field are three pelage characters (distinctness of tail bands, stripes on the nape and stripes on the shoulder). Only two morphological characters (intestine length and cranial volume) are unambiguous and demonstrate no overlap in distribution between domestic cats and wildcats. A linear discriminant analysis with forward selection of variables showed that only five skull variables are necessary to distinguish all four groups (subspecies · sex). Additionally, the high degree of correlation between most of the 49 variables examined (as indicated by PearsonÕs r correlation matrix) speaks against the utility of measuring such high numbers of characters in the future. Principal component analysis (PCA) enabled the subspecies to be separated clearly. The first PCA axis was highly correlated with variables characterizing overall body size, thus separating male and female into wildcats and domestic cats. Even when the chief differentiating characters are missing, the PCA still resulted in a good separation of subspecies. None of the genetically determined hybrids could have been deciphered unambiguously using the morphological characters still intact after a road death. Hybridization seems to occur whenever wildcats change their ecological function and become field cats. The impulse to hybridize seems to come much more from the wildcat side than the side of feral cats, and deforestation represents the major threat to the wildcat.

“…Les valeurs obtenues sont les suivantes : (N = 6) 2,403 ä 2,433 (Braunschweig, 1963) 1G6 (Liips, 1971) Ces valeurs, legerement inferieures aux miennes, proviennent de la methode de mensuration differente de celle que j'emploie, mais rindice intestinal reste neanmoins comparable. Le chat domestique n'etant pas issu de F. silvestris, il serait errone d'interpreter les chiffres enonces dans ce travail autrement que pour ridentification du chat forestier, pour le distinguer des chats domestiques retournes a la vie sauvage, et qui pourraient etre confondus avec le precedent de par leur morphologie externe.…”

Skull characters of wildcats (Felis silvestris), classed as ‘old’, ‘recent’ or ‘modern’, depending on collection date, were compared with those of domestic cats (F. catus) and hybrids, using Fisher Linear Discriminant Functions, Principal Component Analyses and Canonical Variates. A key is derived for classification of individual (unknown) skulls. All analyses indicate that ‘recent’ and ‘modern’ wildcats were different from those collected earlier, and implied marked changes in the rate of hydridization during this century. We suggest that the older wildcat populations were a relatively ‘pure’ form but more recent populations contain a significant hybrid component. Although there may be a trend towards re‐establishment of the earlier type, an alternative conclusion is that the ‘pure’ form of wildcat is effectively extinct in Scotland.
