The organization of the vomeronasal system (VNS) of fetal, newborn, and adult cats was investigated by microdissection and microscopic examination of sections stained conventionally or with lectins (UEA-1, LEA) or antibodies against proteins Gα(i2) (associated with vomeronasal receptor type1) and Gα(o) (associated with receptor vomeronasal receptor type2). The feline VNS is morphologically similar to that of other mammals. Staining with lectins and anti-Gα(i2) was uniform throughout the sensory epithelium of the vomeronasal organ, and throughout the nervous and glomerular layers of the accessory olfactory bulb (AOB); anti-Gα(o) stained no VNS tissue. This organization places the cat together with several other domestic or farm animals (dog, horse, sheep, goat, pig) in a group of mammals with just a single path of communication between the sensory epithelium of the vomeronasal organ and AOB, in contrast to the two-path model found in rodents and other mammals (in which apical and basal sensory epithelium layers project to rostral and caudal AOB areas, respectively). However, the cat differs from the sheep and pig in that the development of its VNS is still incomplete at birth.
采用微解剖和常规染色、凝集素（UEA-1、LEA）或针对蛋白 Gα(i2)（与 V1 型嗅觉受体相关）和 Gα(o)（与 V2 型嗅觉受体相关）抗体染色切片的显微镜检查，研究了胎儿、新生和成年猫的犁鼻器系统（VNS）的组织。猫的 VNS 在形态上与其他哺乳动物相似。凝集素和抗 Gα(i2)染色在犁鼻器的感觉上皮和副嗅球（AOB）的神经和肾小球层中均匀分布；抗 Gα(o)未染色 VNS 组织。这种组织排列将猫与其他几种家养或农场动物（狗、马、绵羊、山羊、猪）归为一组，这些动物的犁鼻器感觉上皮和 AOB 之间只有一条单一的通讯途径，与在啮齿动物和其他哺乳动物中发现的两条途径模型（其中犁鼻器的顶端和基底感觉上皮层分别投射到 AOB 的头侧和尾侧区域）形成对比。然而，与绵羊和猪不同，猫的 VNS 在出生时仍未完全发育。
