Felidae the Felidae, grouped according to the traditional phenotypical classification with the corresponding genotypical lineages indicated. It includes all of the currently living cat species. There is considerable variation in the taxonomy used for the wildcat. It used to be regarded as "Felis silvestris" with distinct subspecies "F. s. silvestris", "F. s. lybica" and "F. s. ornata" in Europe, Africa and Asia respectively. Since 2017, the IUCN Cat Specialist Group recognises "silvestris" and "lybica" as distinct species. The phylogenetic relationships of extant felids are shown in the following cladogram, based on the molecular phylogenetic analysis of Johnson et al. (2006). The
Animals (Scientific Procedures) Act 1986 be done through non-animal or in-vitro methods. The project must also pass an ethical review panel which aims to decide if the potential benefits outweigh any suffering for the animals involved. ASPA involves three levels of regulation — person, project, and place. The 'person' level is achieved by the granting of a "personal licence" (PIL, procedure personal licence) to a researcher wishing to carry out regulated procedures on a protected animal. Having undergone a defined sequence of training, a researcher can apply for a PIL permitting specified techniques to be carried out on named species of animals. The 'project' level
