This study evaluated radiographic and gross morphometry of lumbar vertebrae (L1-L7) in six adult domestic shorthair cats. Measurements included lamina, pedicle, vertebral foramen, body, spinous and transverse processes, articular, and accessory structures. Morphometric trends showed progressive enlargement from L1 to L6, with tapering at L7. Posterior features generally exceeded anterior dimensions. Bilateral symmetry and strong modality concordance were observed, with minor discrepancies due to radiographic distortion. The absence and reduction of accessory processes at L6-L7 suggest structural transition toward sacral regions. These findings offer vital anatomical reference for imaging, orthopaedic intervention, and comparative vertebral studies in small animal anatomy.
