The G-banded karyotype of the Iriomote cat, Felis iriomotensis, was found to be indistinguishable from that of F. bengalensis, F. viverrinus, and F. concolor. The karyotype of these four cats is, however, distinguishable from karyotypes of all other species of cats whose chromosomes have been studied. Silver-staining showed nucleolar organizing regions on the satellited stalks of the E1 chromosomes. Based on morphological and cytogenetic parameters F. iriomotensis is probably most closely related to F. bengalensis, the only other wild felid native to Japan.
发现西表猫（Felis iriomotensis）的G带核型与豹猫（F. bengalensis）、渔猫（F. viverrinus）和美洲狮（F. concolor）的核型无法区分。然而，这四种猫的核型与所有其他已研究过染色体的猫科动物的核型是有区别的。银染显示E1染色体随体柄上有核仁组织区。根据形态学和细胞遗传学参数，西表猫可能与豹猫关系最为密切，豹猫是日本唯一的另一种野生猫科动物。
