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 of regulation is governed by the granting of a "project licence" (PPL) to a suitably qualified senior researcher. The PPL details the scope of the work to be carried out, the likely benefits that may be realised by the work, and the costs involved in terms of the numbers and types of animals to be used, and the harm that might be caused to the animals. Typically a large and detailed document, the PPL precisely defines which techniques may be applied to particular animals and for what purpose. Finally, the 'place' where regulated procedures are carried out is controlled by
