The ultrastructure of the ear of the newborn native cat was examined to determine whether the vestibular system contained sensory receptors. A sensory region, presumably the utricle, was identified in each ear and consisted of a discrete population of otoliths overlying a sensory epithelium which possessed kinocilia and stereocilia. The remainder of the vestibular system did not appear to be developed anatomically. The newborn cat has rudimentary vestibular, olfactory, and mechanoreceptors (Merkel cells), and these structures may aid the newborn marsupial in the journey from the urogenital sinus to the pouch and in locating the teat.
对新生本土猫的耳部超微结构进行了检查，以确定前庭系统是否包含感觉感受器。在每只耳朵中都识别出一个感觉区域，推测为椭圆囊，它由覆盖在具有动纤毛和静纤毛的感觉上皮上的离散耳石群体组成。前庭系统的其余部分在解剖学上似乎未发育。新生猫具有发育不全的前庭、嗅觉和机械感受器（默克尔细胞），这些结构可能有助于新生有袋动物从泌尿生殖窦到育儿袋的旅程以及找到乳头。
