Marbled polecat of at least 30% in the previous 10 years. In 1996, it had been considered a species of least concern. The decline in marbled polecat populations thought to be due to habitat destruction (cultivation) and reduction in available prey by use of rodenticides. In Pakistan, it is listed as an endangered species. The marbled polecat was once sought for its fur, generally known as "fitch" or more specifically, "perwitsky" in the fur trade.<ref name="http://www.merriam-webster.com/dictionary/perwitsky"></ref> In 1945, Kabul shopkeepers were reported to have kept marbled polecats to exterminate rodents. Their journals also show some developed an adverse reaction to the strong
European polecat deter intrusion. During the summer period, the diets of wild polecat-mink hybrids are more similar to those of minks than to the polecats, as they feed predominantly on frogs. During the winter, their diets overlap more with those of polecats, and will eat a larger proportion of rodents than in the summer, though they still rely heavily on frogs and rarely scavenge ungulate carcasses as polecats do. The European polecat can also hybridise with the Asian steppe polecat or the North American black-footed ferret to produce fertile offspring. European-steppe polecat hybrids are very rare, despite their sympatry in several areas.
