The Anomalist has a link to a fascinating article that speaks for itself:
Britain's 'Big Cat X Files' Revealed Telegraph. There have been more than 100 sightings of exotic and unidentified animals in England since 2005, according to Natural England, a government agency responsible for investigating such incidents. Of these, 38 were "big cats" reports. Though their investigations have yet to find conclusive proof of the presence of the mysterious creatures, they show the extent to which Natural England takes the reports seriously. Other reported animals include 14 coypus, a large South American rodent; 28 wild boar; and 2 cases of raccoon dogs, which are native to Asia and Russia.
