Regarding the displaying of the main differences between the pelvic limb of rabbit and cat.
Our work was performed on 10 New Zealand rabbits () and domestic cats () with variable ages and of both sexes. After weighing of the animals, sedation, and anesthesia, the animals were examined radiographically. The bones of the pelvic limb were prepared, measured for its length/cm then described and compared.
The iliac tuberosity and the conversion of the acetabular notch into foramen were characteristics of Os coxae of the rabbit. The intertrochanteric crest was detected on the femur of the cat. In the rabbit, the leg interosseous space was located in the proximal third of this region while in the cat, it was extended along its length. The first metatarsal was undeveloped in the cat but was absent in the rabbit so metatarsal were four in the rabbit and five in the cat. The digits of the pelvic limbs in both animals were four in number. The distal sesamoid was single, transversely situated, and shuttle-shaped in rabbit but it was absent in cat.
So, the chief points of variation between the pelvic limb bones of rabbit and cat enabled us to keep away the commercial fraud and facilitated their use as an animal model for education purposes.
阐述兔和猫后肢的主要差异。
我们选取了10只不同年龄、性别的新西兰兔和家猫进行研究。对动物称重、镇静及麻醉后，进行X线检查。制备后肢骨骼，测量其长度（厘米），然后进行描述和比较。
兔的髋骨具有髂结节以及髋臼切迹转变为孔的特征。在猫的股骨上可检测到粗隆间嵴。兔的小腿骨间隙位于该区域近端三分之一处，而猫的小腿骨间隙沿其全长延伸。猫的第一跖骨未发育，而兔没有第一跖骨，因此兔有四块跖骨，猫有五块跖骨。两种动物后肢的趾数均为四个。兔的远籽骨单一，横向位于并呈梭形，而猫没有远籽骨。
因此，兔和猫后肢骨骼的主要差异点使我们能够避免商业欺诈，并便于将它们用作教育目的的动物模型。
