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
Steppe polecat and black-footed ferret, with which it is thought to have shared "Mustela stromeri" as a common ancestor. The steppe polecat likely diverged from the European polecat 1.5 million years ago based on IRBP, though cytochrome b transversions indicate a younger date of 430,000 years. As a species, the steppe polecat represents a more specialised form than the European polecat in the direction of carnivory, being more adapted to preying on larger rodent species; its skull has a stronger dentition, its projections are more strongly developed and its muscles of mastication are more powerful. The steppe polecat's growth rate is also
