Objective: Regarding the displaying of the main differences between the pelvic limb of rabbit and cat, Materials and methods: our work was performed on ten New Zealand rabbits (Oryctolagus cuniculus) and domestic cats (Felis domestica) 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 describe and compared. Results: The iliac tuberosity and the conversion of the acetabular notch into foramen were characteristic to 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 absent in rabbit so metatarsal were four in 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. Conclusion: 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.
