The present work indicates that the Processus suprahamatus of the scapula is longer in rabbit (1.4 cm) than in cat (0.4 cm). The ratio between the Fossa supraspinata and infraspinata is 1:2 in rabbit, while in cat it is 1:1. The humerus has a rounded Foramen supratrochleare in rabbit, and a slit like Foramen supracondylare in cat. The Trochanter major projects above the level of the head of the femur in rabbit, but the two are situated at the same level in cat. The Cochlea tibiae has three sagittal grooves in rabbit and two oblique grooves in cat. The dry matter and calcium percent of the studied long bones are higher in rabbit than in cat, on the contrary, the ash and phosphorus percent are lower in rabbit than in cat. The summation of the percentage of calcium and phosphorus of each examined bone is higher in rabbit than the corresponding bone in cat.
