This study was conducted to produce a three-dimensional model of the thorax and lower respiratory tract in Van cats, to reveal their morphometric properties, and to investigate the anatomical structure of this region in more detail. A total of 16 adult Van cats (8 males and 8 females) were used in the study. The thoracic region of the cats was scanned using multidetector computed tomography device. The images of the scanned region were transferred to the MIMICS 20.1 software that creates three-dimensional reconstruction in order to produce the models. The morphometric measurements were obtained from these models and the index values were calculated. When the data were analysed in terms of sexual dimorphism, significant differences were determined between the sexes in terms of transverse diameter of the thoracic cavity in apertura thoracis cranialis (T2) (P < 0.05), minimum width of apertura thoracis cranialis (T3), and height of the thoracic cavity in thoracis cranialis (H1) (P < 0.01). The index values of the data revealed a significant difference between the sexes only in terms of the thoracic index 2 (P < 0.05). The 7th sternebra was shorter and more flattened than the other sternebrae in Van cats. In conclusion, three-dimensional models of the thorax and lower respiratory tracts of Van cats were produced in the study. It is thought that the data of the study may be useful in clinical practice and academic studies in the field of veterinary medicine.
Three-Dimensional Morphometric Analysis of the Metatarsal and Phalangeal Bones in Van Cats

The aim of this study was to perform three-dimensional reconstruction of the metatarsal and phalangeal bones using computed tomography, to obtain osteometric data and to determine biometric differences in terms of sexual dimorphism in the obtained measurements in Van cats, an endemic species living in the Van province region of eastern T & uuml;rkiye and named after this region. Computed tomography images of a total of 16 adult and healthy Van cats, eight females and eight males, were used in the study. Three-dimensional modelling of the images and osteometric measurements were obtained using MIMICS 20.1 software. When the osteometric data of the bones were analysed, it was observed that all of the morphometric measurements of metatarsal, phalanx media, phalanx distalis and phalanx proximalis bones, except the greatest breadth of the distal end of the phanax proximalis-III, the greatest breadth of the proximal end of the right phalanx proximalis-II, left phalanx proximalis-IV and left phalanx proximalis-V, were higher in male cats than females. The length order of the metatarsal bones in Van cats was found as IV, III, V and II, respectively. It was determined that there were positive and significant correlations between the osteometric measurement parameters of metatarsal and phalangeal bones with age and body weight. In conclusion, basic morphological images and osteometric data of the metatarsal and phalangeal bones in Van cats were obtained. These findings will be valuable for studying anatomy, aiding veterinary medicine students in clinical practice and contributing to the fields of zooarchaeology and veterinary forensic anthropology.
