In the 1970s and 1980s, the Russian zoologists Geptner, Gromov and Baranova disagreed with this classification. They emphasized the differences of skins and skulls at their disposal and the ones originating in Southeast Asia, and coined the term Amur forest cat, which they regarded as a distinct species. In 1987, Chinese zoologists pointed out the affinity of leopard cats from northern China, Amur cats and leopard cats from southern latitudes. In view of the morphological similarities they did not support classifying the Amur cat as a species.
