Fourteen wildcats Felis siluestris silvestris Schreber, 1777 were trapped in winter 1993 in the southern part of the Swiss Jura Mountains as a bycatch. During the last thirty years of protection the presence of wildcats in Switzerland could be confirmed by a few dead-found individuals, but the status of the species was unknown. This is the first indication of an existing population. Even though the upper distribution limit of wildcats in central and western Europe is described at 800 m a.s.l., most individuals were caught in altitudes from 970 to 1200 m. We registered a higher catching success in south exposed beech forest and in the sycamore forest, than in the northern exposed Norway spruce forest. During snowcover above 30 cm no wildcats were caught. The capture sites were located within distances of 200-1900 m from human settlements.
Wildcats Felis silvestris Schreber, 1775 were captured for radio collaring as a part of a study of their spatial distribution and social organisation in southern Slovenia between 1999 and 2001. Double-door box traps, with a roof that bears easily break (bear permeable traps), have been used to capture individuals. The distances between traps were between 550 to 2200 m. They were set out on logging roads and narrow trails in the forest. Nine wildcats, one lynx Lynx lynx (Linnaeus, 1758) and one feral cat were caught as target species and 19 badgers Meles meles and one bear cub Ursus arctos as non-targets. The catching success was 1 wildcat/58 trap-days and seems to be in correlation with the lunar cycle. Overall, 7 males and 2 female wildcats were captured which might indicate sex biased trapping selection. Methodological improvements shortened the time of handling procedures. Improved field protocols as well as restraining and immobilisation procedures increased reliability and safety of drug administrations, decreased potential chances for injuries and reduced overall stress of captured animals.
