Bluebeard (Blaubart in the original print), a deformed local cat, is convinced that humans(cat slang: "can-openers") are responsible for the death and other recent murders. Francis disagrees with this assessment, convinced that the slash on Sascha's
Felidae based on phenotypical features: the Felinae, the Pantherinae, the Acinonychinae (cheetahs), the extinct Machairodontinae, and the extinct Proailurinae. Molecular phylogenetic analysis suggests that living (extant) felids fall into eight lineages (clades). The placement of the cheetah within the Puma lineage invalidates the traditional subfamily Acinonychinae, and recent sources use only two subfamilies for extant genera. The eight lineages divide between these as follows: The last four lineages are more related to each other than to any of the first four, so form a clade within the subfamily Felinae of family Felidae. The following is the complete list of genera within
