Analyses were made of 118 skull measurements of adult wild cats Felis silvestris Schreber, 1777 from Bulgaria, taken on 24 males, 20 females, and 10 animals whose sex was not known in advance. Group (cluster) analysis of cases, factor analysis, and stepvise discriminant analysis were adapted. The cluster analysis of cases indicated a high level of sex mixture (up to 40%), which suggested the importance of the outliers in the data. Six keys to sexual dimorphism, of very high statistical significance were produced, through the stepvise discriminant analysis. They included from 9 down to 1 variables each, which provided from 100% down to 93.8% of correct sex classification of wild cat skulls.
