Abstract

On the topic of the manifestation of main differences between the thoracic limb of rabbit and cat, our research was carried out on ten adult New Zealand rabbits (Oryctolagus cuniculus) and domestic cats (Felis domestica) of both sexes. The animals were radiographically examined. Also, the bones were prepared, measured (length/cm), described and compared. The gross morphological study showed the presence of processus hamatus and suprahamatus of the scapula in both species. Supratrochlear foramen was observed in rabbit while in cat the supracondyloid foramen was present. The interosseous space of the forearm region was proximally located in rabbit but in cat, it was extended along the forearm region. The carpal bones were nine and seven in rabbit and cat respectively. In both species, Metacarpals and digits of the thoracic limbs were five in number. The distal phalanx was characterized by unguicular process and enclosed in the claw. The distal sesamoid was absent in cat. So, the major points of dissimilarity between the appendicular skeleton of rabbit and cat helped us to keep off the commercial fraud.
