Abstract
The Scottish population of the European wildcat (Felis silvestris), the only remaining native felid species in the United Kingdom, is critically endangered and was declared functionally extinct by the International Union for Conservation of Nature in 2019. This retrospective study investigated the causes of morbidity and mortality reported in the United Kingdom captive wildcat population from 01 January 2000 to 31 December 2021. The aim was to assess the health and welfare of ex situ wildcats and, by making recommendations for management based on study findings, contribute to the sustainability of the population under managed care. Younger wildcats accounted for 85.7% of all morbidity cases (kittens, 7/77; young adults, 59/77), and the gastrointestinal (67.5% [52/77]), musculoskeletal (10.4% [8/77]), and integumentary (5.2% [4/77]) systems were most affected. Mortality was primarily associated with disease of the gastrointestinal (13.5% [12/89]), respiratory (13.5% [12/89]), neurological (5.6% [5/89]), and renal (5.6% [5/89]) systems. One quarter of all the histopathology examinations reported gastritis with associated Helicobacter-like organisms, often combined with pancreatitis or cholangiohepatitis. Neonates represented 25% (22/89) of all deaths, a high percentage compared with that of previous reviews in other nondomestic felids.
